please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Step-by-step explanation:
C says -3.5 < -2.5
For negatives the smallest number is the greater.
Answer:
C
Step-by-step explanation:
When numbers are negative, you want to choose the number closest to zero. In this case, -3.5 is farther from 0 than -2.5, so C is the correct answer.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
A submarine is descending to examine the seafloor 2,100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarine's elevation and time.
Another submarine’s descent can be represented as y=-240x, where y is the elevation and x is time in hours. How long will it take this submarine to make the descent?
Answer:
-1050
Step-by-step explanation:
I know the answer because descending means going down so 2100 is the big number and its negative to if you do -2100 divided by 2 then you will get -1050.
It would take the submarine 8.75 hours to make the descent of 2100 feet.
Linear equationA linear equation is in the form:
y = mx + b
where m is the rate of change, y, x are variables, and b is the y intercept.
Let y represent the level of the submarine after x hours.
It takes the submarine 2 hours to make a descent of 2100 feet, hence:
y = mx
-2100 = 2m
m = -1050
y = -1050x
Given the equation y = -240x, for 2100 feet descent:
-2100 = -240x
x = 8.75 hours
It would take the submarine 8.75 hours to make the descent of 2100 feet.

x = 5
Step-by-step explanation:
Now to solve for our equation:
110 - 4x = 130 - 8x
Subtract 110 from both sides: (110 - 110) - 4x = (130 - 110) - 8x
Simplify: -4x = -8x + 20
Add 8x to both sides: (-4x + 8x) = (-8x + 8x) + 20
Simplify: 4x = 20
Divide both sides by 4: (4x / 4) = (20 / 4)
Simplify: x = 5

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.
b) The correct expression is given as follows: -8.6b + 28.
How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.
Then, to simplify the expression, we combine the like terms, as follows:
b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

If a value of 80.8° is added to the data, how does the range change?
Answer:
The original data set would be:
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
So to find the range you would do:
105 - 57 which equals 48.
So the range for the original data set would be 48.
The new data set adding 80.8:
57, 58, 61, 66, 71, 77, 80.8, 82, 91, 95, 100, 102, 105
So to find the range for the new data set you would do:
105 - 57 which would still equal 48.
So the range for the new data set would be 48.
The range for the original and new data set stayed the same.

what is an equation of the line that passes through the points (4,−3) and (2,−4)
The equation of the line that passes through the points (4,−3) and (2,−4) is y = 1/2x - 5
How to determine the equation of the lineThe general formula for calculating the equation of a line is expressed with the given equation;
y = mx + c
the parameters of the equation are;
y is a point on the y -axis.m is the gradient or slope of the line.x is a point on the x - axis.c is the y - intercept of the line.From the information given, we have;
Slope, m = y₂ - y₁/x₂ - x₁
Substitute the values
Slope, m = -4 - (-3)/ 2 - 4
subtract the values
Slope = -1/-2 = 1/2
Then, the intercept is;
-4 = 1/2(2) + c
c = -4 - 1 = -5
