is a transformation involving the addition, subtraction, multiplication, or division of or by a constant.
Yes, a transformation can involve the addition, subtraction, multiplication, or division of or by a constant. In fact, these operations are commonly used in mathematical transformations.
For example, adding a constant to each value in a set of data is a common way to shift the entire set of values up or down. Multiplying each value in a set of data by a constant is a common way to stretch or shrink the data. Subtraction and division can also be used in transformations, depending on the context. However, it is important to note that not all transformations involve these operations.
Some transformations may involve more complex operations, such as exponentiation or logarithmic transformations. So, the short answer is yes, but the long answer is that it depends on the specific transformation being used.

See below.
Step-by-step explanation:
The range of a graph is the span of y-coordinates the graph covers.
From the graph, we can see that the graph covers all y-values between the values of y=-8 and y=7.
Therefore, the range is all of the numbers in between them including them.
In interval notation, this is:
\([-8,7]\)
We use brackets instead of parentheses because we include the numbers.
And in set notation, this is:
\(\{y|-8\leq y\leq 7\}\)
Answer:
Hey there!
The range is the possible y values.
Thus, we see here that the range is all numbers from -8 to 7.

Question 5 ? Question What does the point (6,0) represent? O the length of time it takes for the height of the plant to reach 72 centimeters O the initial amount of plant food O the amount of plant food used each day O the length of time it takes for Ryan to use all the plant food
The point (6,0) represent the length of time it takes for Ryan to use all the plant food
What is Time ?
Time is a continual and continuous series of events that take place one after another, from the past through the present and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.
The location and value of x at which the function represented by f(x) equals zero are known as the x-intercept.
The height of the bean sprout and the quantity of plant food added were both measured, per the information given.
Given the observational aspect of the experiment, we know that the function of the variable y = f(x) is the height of the bean sprout, and the variable x, which may be chosen by the researcher, is the amount of the additional plant food.
As a result, the x-intercept, which represents the experiment's starting position (represented by the natural numbers of y = 0), shows how much plant food was initially added to the soil.
Hence, The point (6,0) represent the length of time

The point (6, 0) represents the initial amount of plant food, which is 0 at this point.
When representing a point in the form (x, y), the x-coordinate typically represents a quantity or value on the horizontal axis, while the y-coordinate represents a quantity or value on the vertical axis.
The point (6,0) means that the x-coordinate is 6, which corresponds to a specific value or measurement along the horizontal axis.
Since the context of the question refers to plant food, the x-coordinate of 6 likely represents a measurement related to the amount of plant food.
The y-coordinate, in this case, is 0, indicating that there is no height or value represented on the vertical axis.
Therefore, (6, 0) represents the initial amount of plant food, which is 0 at this point.

for a statistics project, judith distributed a questionnaire and asked her classmates to fill it out. 7 of them did. is this sample of the students in the class likely to be representative?
It depends on several factors, including the size of the class and the method used to select the sample of 7 students.
If the class size is small, say less than 20 students, then a sample of 7 students might be representative if the selection method used is random. In this case, each student in the class would have an equal chance of being selected, and the sample would likely represent the diverse opinions and characteristics of the entire class.
However, if the class size is large, say over 100 students, a sample of 7 students is unlikely to be representative of the entire class. In this case, the sample may not accurately reflect the opinions and characteristics of the entire class, and there is a higher likelihood of selection bias.

The value of c in the equation 7c - cy = 10x will give a line with slope +5 is -2.
We can rewrite the equation as:-
-cy = 10x - 7c
y = (-10/c) x + 7
Now the equation is in slope-intercept form which is given by:-
y = mx + b
Where,
m represents the slope of the line
b represents the y-intercept of the line
(x,y) represents ordered pair of each point of the line
Comparing both the equations, we get
m = -10/c
b = 7
We have to get m = +5
Hence, equating both the values of m, we get

Step-by-step explanation:
Answer:
The answer is 87°
Step-by-step explanation:
A quadrilateral has an interior angle sum of 360°.
Given that three of the four angles in a quadrilateral are 89°, 80°, and 104°, we can create the following equation where x is the missing angle:
89° + 80° + 104° + x° = 360°.
All you have to do is add all the measures up and subtract from 360°.
89° + 80° + 104° + x° = 360° →
273° + x° = 360° →
x° = 87°.
Also, for any polygon, the interior angle sum is (n – 2) × 180°, where n is the number of sides.
A quadrilateral is a polygon with four sides so it's interior angle sum must be
(4 – 2) × 180° = 2 × 180° = 360°.

O {-1, -1, 1,3}
O {-4, -2, 2, 2}
O{-4, -2,2}
Answer:
(-4,-2,2)
Step-by-step explanation:
The range of the relation R is {-4, -2, 2}.
Correct option is 4.
What is Range?It is seen to be the best practice to define the word "range" the first time it is used in a book or article because it might have several different meanings. When the word "range" is used in older literature, it frequently refers to what is today known as the co domain. If more recent texts use the phrase "range" at all, they typically do so to refer to what is now known as the image. Several contemporary books don't use the word "range" at all to avoid any misunderstandings.
As per the given data:
Relation R is {(3,-2), (1, 2), (-1, -4), (-1, 2)}.
The collection of all a function's outputs defines its range.
The number on the y coordinate is what we know to be the range.
It is given that
r {(3, -2), (1, 2), (-1, -4), (-1, 2)}
Here the range is
{-2, 2, -4, 2}
As 2 is repeated, take it once
By rearranging from least to greatest
R: {-4, -2, 2}
∴ The range is {-4, -2, 2}.
Hence, the range of the relation R is {-4, -2, 2}.

Describe the similarities and differences between finding the slope of a linear equation from a graph that has x and y scales that are 1:1, and from a graph that has x and y scales that are not 1:1 (say your x and y scales are 2, 4, 6).
Using the concept of the slope of a linear function, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points in the graph of a function, the slope is given by change in y divided by change in x, hence:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.More can be learned about linear function concepts at https://brainly.com/question/24808124

Explain what your variable represents.Movie Mania requires customers to pay a sign-up fee of $20, and charges $4.00 to rent a DVD. Hurricane Video is free to join, but DVDs cost $6.00 to rent. Write and solve an equation to find the number of DVDs you would have to rent in order for both stores to charge the same. Explain what your variable represents.
Answer:
10
Step-by-step explanation:
For movie mania:
Sign-up fee = $ 20
Rent for 1 DVD = $ 4.00
For Hurricane video:
Sign-up fee = 0
Rent of 1 DVD = $ 6.
Let \(n\) be the number of DVDs to rent in order for both stores to charge the same.
For movie mania, charge to rent \(n\) DVDs = Sign-up fee + rent of \(n\) DVDs
=20+4n
For Hurricane movie, charge to rent \(n\) DVDs = Sign-up fee + rent of \(n\) DVDs
=0+6n=6n
Now, for both stores to charge the same, both the charges must be equal, we have
6n=20+4n
\(\Rightarrow 6n-4n=20\)
\(\Righatarroe 2n=20\)
\(\Rightarrow n =20/2=10\)
Hence, the required number of DVDs to rent is 10 in order for both stores to charge the same.

If Gabe took a pay cut to reduce the overhead costs to $8,000 per month, how many fewer balls would the company have to sell to break even. (There are multiple ways to get this result).
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Selling price= $60
Unitary variable cost= $28
Fixed costs= $15,000
First, we need to calculate the average total cost:
Average cost= total cost / number of units
For example, for 1 unit and 10,000 units:
1 unit:
Average cost= 15,028/1 = 15,028
10,000 units:
Average cost= (15,000 + 28*10,000) / 10,000
Average cost= $29.5
Now, we can calculate the break-even point in units:
0= (60*x) - (28*x) - 15,000
x= number of units to break-even
0= 32x - 15,000
15,000/32= x
468.75=x
break-even point in units= 469
For the desired profit of $10,000:
10,000 = (60*x) - (28*x) - 15,000
25,000= 32x
781.25= x
Break-even point= 782 units
Finally, fixed costs dropped by $8,000:
0= 32x - 7,000
x= 7,000/32
x= 218.75
Break-even point= 219
Difference= 250 units

When you rewrite an addition or subtraction problem using the Distributive Property, you have to ______ both values by a common factor, usually the GCF.
When you rewrite an addition or subtraction problem using the Distributive Property, you have to factor out both values by a common factor, usually the GCF.
This process involves identifying the common factor (the greatest common factor, or GCF) of the terms and then applying the Distributive Property to rewrite the expression. This common factor can be the greatest common factor (GCF) if it exists, but it does not have to be. The goal is to find a factor that is common to both terms, so that it can be factored out and the expression can be simplified.For example, consider the expression 6 + 8. We can rewrite this using the distributive property by factoring out 2, which is a common factor of both 6 and 8:6 + 8 = 2(3) + 2(4)Then, we can simplify the expression by adding the like terms:2(3) + 2(4) = 6 + 8 = 14Note that in this example, we factored out the common factor 2, which is not the GCF of 6 and 8 (the GCF is 2).

Explain to someone who has forgotten the even-odd properties of sinusoidal functions how the addition and subtraction formulas can determine this characteristic for f (x) = sin(x) and g(x) = cos(x). (Hint: 0 − x = − x )
Therefore, From the above equations, we can see that sin(x) is odd, and cos(x) is even. To summarize:
sin(-x) = -sin(x) (odd function), cos(-x) = cos(x) (even function)
To understand the even-odd properties of sinusoidal functions, let's first recall that an even function satisfies f(-x) = f(x) and an odd function satisfies f(-x) = -f(x).
Now, consider the sinusoidal functions f(x) = sin(x) and g(x) = cos(x). We can use the addition and subtraction formulas for sine and cosine to determine their even-odd properties.
The addition and subtraction formulas are as follows:
1. sin(a + b) = sin(a)cos(b) + cos(a)sin(b)
2. cos(a + b) = cos(a)cos(b) - sin(a)sin(b)
Let a = x and b = -x. Then, we get:
1. sin(x - x) = sin(x)cos(-x) + cos(x)sin(-x)
2. cos(x - x) = cos(x)cos(-x) - sin(x)sin(-x)
Since sin(-x) = -sin(x) and cos(-x) = cos(x), we can simplify:
1. sin(0) = sin(x)cos(x) - cos(x)sin(x) => 0 = 0
2. cos(0) = cos(x)cos(x) + sin(x)sin(x) => 1 = cos^2(x) + sin^2(x)
Therefore, From the above equations, we can see that sin(x) is odd, and cos(x) is even. To summarize:
sin(-x) = -sin(x) (odd function), cos(-x) = cos(x) (even function)
