The coordinate plane below shows the location of rectangle TUVW.
rectangle TUVW is to be dilated by a factor of 3, with the center of dilation at the point (1,0). drag and drop the the correct answers into each box.

Answer:

(2,-1)

Step-by-step explanation:

We can use substitution to solve this system of equations. Since x is already solved for in the second equation, we can substitute 2y + 4 for x in the first equation:

4(2y + 4) + 2y = 6

Simplifying the left side:

8y + 16 + 2y = 6

Combining like terms:

10y + 16 = 6

Subtracting 16 from both sides:

10y = -10

Dividing both sides by 10:

y = -1

Now that we know y, we can use the second equation to find x:

x = 2y + 4

x = 2(-1) + 4

x = 2

Therefore, the solution to the system of equations is (x, y) = (2, -1).

The correct answer choice is (2, -1).

1 cm = 10 mm. Length of book : 28 cm. Length of book = 280 mm. This shows that measurements in mm are the same but look to have a higher number .

The conversion factor provided states that 1 cm is equal to 10 mm, which means that 1 cm is made up of 10 individual millimeters.

The length of my book in when measured in millimeters is 280 mm.

In centimeters, this is therefore:

= 280 mm / 10 cm /mm

= 28 cm

Although the numerical value appears higher when expressed in millimeters, it is important to note that the actual length of the book remains the same.

Answer:

2,012 is greater than 30

Step-by-step explanation:

The correct solution for the inequality is k > -9.

Given is an inequality -2k + 12 < 30, we need to solve for k,

To solve the inequality -2k + 12 < 30 for k, follow these steps:

Subtract 12 from both sides of the inequality to isolate the term with 'k':

-2k + 12 - 12 < 30 - 12

-2k < 18

Divide both sides by -2, but remember that when you divide an inequality by a negative number, the direction of the inequality sign flips:

(-2k)/(-2) > 18/(-2)

k > -9

So, the correct solution for the inequality is k > -9.

Among the options you provided, the correct answer is: k > -9.

Answer:

y= -x²-4x+2

Step-by-step explanation:

write in vertex form

a(x-h)²+k

in our case h = -2 and k= 6

y=a(x+2)²+6

now we just need to solve for a. we know that when x= 1 y = -3. plug these values in and solve for a

-3= a(1+2)²+6

-9=9a

a= -1

thus the formula is -(x+2)²+6

generally, teachers want things in standard form, so expand the exponent and simplify.

-(x²+4x+4)+6

y= -x²-4x+2

Answer:

\(y = -x^2 - 4x + 2\)

Step-by-step explanation:

The equation of a parabola in vertex form is:

\(y = a(x - h)^2 + k\)

where (h, k) is the vertex of the parabola.

In this case, the vertex is (-2, 6), so h = -2 and k = 6.

We also know that the parabola passes through the point (1, -3).

Plugging these values into the equation, we get:

\(-3 = a(1 - (-2))^2 + 6\)

\(-3 = a(3)^2 + 6\)

-9 = 9a

a = -1

Substituting a = -1 into the equation for a parabola in vertex form, we get the equation of the parabola:

\(y = -1(x + 2)^2 + 6\)

This equation can also be written as:

\(y = -x^2 - 4x -4+6\\y=x^2-4x+2\)

Answer:

  multiply them

Step-by-step explanation:

Units work in algebraic equations the same way that variables do. They can be multiplied and divided as though they were variables.

For units conversion, we want to change the units without changing the value of the quantity. We do that by multiplying by a unit conversion factor that has a numerator equal to its denominator.

__

We know ...

  1 cup = 8 fl oz

  2 cups = 1 pint

These relations can be written as the conversion factors ...

  (8 floz)/(1 cup)   and   (2 cups)/(1 pint)

Multiplying these together, the units of cups cancel, leaving fluid ounces per pint.

  \(\dfrac{8\text{ fl oz}}{1\text{ cup}}\times\dfrac{2\text{ cup}}{1\text{ pint}}=\dfrac{8\cdot2\text{ fl oz$\cdot$cup}}{1\cdot1\text{ pint$\cdot$cup}}=\boxed{\dfrac{16\text{ fl oz}}{1\text{ pint}}}\)

Answer:

B. 40

Step-by-step explanation:

What do you understand by sample size; a sample size is a little portion of a large number we which to investigate. Imagine we wanted to know the electricity consumption of people in a town of 200million people sometimes we could do that be investigating that of 50million especially when you know the conditions would be no different from others. In this sense the sample size is 50 million because that's the one we are investigating.

Similarly our concern of interest for investigation is 40, so that's the sample size.

Answer:

We are given the function S = m^2 + 6m + 8 which models the growth of book sales in m months, where S is an amount in thousands of dollars. We want to find in how many months book sales reach $80,000.

We can set up an equation as follows:

S = m^2 + 6m + 8 = 80

Subtracting 80 from both sides, we get:

m^2 + 6m - 72 = 0

We can factor this quadratic equation as:

(m + 12)(m - 6) = 0

This gives us two possible solutions:

m + 12 = 0 or m - 6 = 0

Solving for m in each case, we get:

m = -12 or m = 6

Since we are looking for a number of months, we can discard the negative solution.

Therefore, book sales reach $80,000 in 6 months.

So, the answer is: 6 months.

The required value of h(9) must be 40 which is the correct answer would be option (3).

The function h(x) has an average rate of change of 7 on the interval 5 ≤ x ≤ 9. This means that, on average, the output of the function increases by 7 for every unit increase in the input.

We are given that h(5)=12, which means that the function has an output value of 12 when the input is 5.

To find the value of h(9), we can use the average rate of change to calculate the expected increase in the function's output over the interval 5 ≤ x ≤ 9.

Since the average rate of change is 7, we expect the function's output to increase by 7 × (9-5) = 28 over this interval.

So, the expected value of h(9) is:

⇒ 12 + 28 = 40.

Therefore, the required value of h(9) must be 40.

The mistake made by the student was using the composition f ° g(x) instead of g ° f(x). The correct form is g( f(0)) = - 9 / 2.

In this question we find two functions, with which we should perform an operation known as composition. Composition consists in substituting the input of a function by the other function. The operation is defined by the following expression:

f ° g (x) = f [g (x)]

Herein we must determine the mistake done by the student on the composition. If we know that f(x) = (3 · x - 7) / 4, g(x) = 2 · x - 1 and x = 0, then the value of g(f (0)) is:

g ° f (x) = g (f (x))

g ° f (x) = 2 · [(3 · x - 7) / 4]  - 1

g ° f (x) = (3 · x - 7) / 2 - 1

g ° f(x) = (3 / 2) · x - 7 / 2 - 1

g ° f(x) = (3 / 2) · x - 9 / 2

g ° f(0) = (3 / 2) · 0 - 9 / 2

g ° f(0) = - 9 / 2

The average velocity for the time period begining when t = 2 and lasting will be 32 feet per second.

The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.

If a ball is thrown straight up into the air with an initial velocity of 55 ft/s, it height in feet after t second is given by y = 55t − 16t².

The total time of flight is given as,

y = 0

55t − 16t² = 0

t (55 - 16t) = 0

t = 0, 3.4375 seconds

The velocity function is given as,

y' = (d/dt) (55t − 16t²)

v(t) = 55 - 32t

Then the average velocity for the time period begining when t = 2 and lasting is given as,

Average velocity = v(3.4375) - v(2) / (3.4375 - 2)

Average velocity = |(55 - 32 x 3.4375) - (55 - 32 x 2)| / (1.4375)

Average velocity = 46 / 1.4375

Average velocity = 32 feet per second

The average velocity for the time period begining when t = 2 and lasting will be 32 feet per second.

Answer:

Step-by-step explanation:

The slope of a line parallel to 2y - 8x = 10 would have the same slope as 2y - 8x = 10, since parallel lines have the same slope.

So to find the slope of the line that is parallel to 2y - 8x = 10, we have to find the slope of 2y - 8x = 10. We can do this by putting the equation in slope-intercept form.

2y - 8x = 10

Add 8x to both sides.

2y = 8x + 10

Divide both sides by 2.

y = 4x + 5

So we can see that the coefficient of x is 4 when the equation is in slope-intercept form. The slope of the 2x - 8x = 10 is 4. Therefore, the slope of the line that is parallel to 2x - 8x = 10 is 4.
