So to get this, you just divide 28 by 7 because when you are funding a fraction of. number and the numerator of that fraction is 1, you divide the original number by the denominator.
28 ÷ 7 = 4
Hope this helps!

Answer:

y  =  (4/3)x - 50  

Step-by-step explanation:

Step 1 :

Identify the independent and dependent variables.

The independent variable (x) is the square footage of floor space.

The dependent variable (y) is the monthly rent.

Step 2 :

Write the information given in the problem as ordered pairs.

The rent for 600 square feet of floor space is $750 :

(600, 750)

The rent for 900 square feet of floor space is $1150 :

(900, 1150)

Step 3 :  

Find the slope.  

m  =  (y₂ - y₁) / (x₂ - x₁)

Substitute (600, 750) for (x₁, y₁) and (900, 1150) for (x₂, y₂).

m  =  (1150 - 750) / (900 - 600)

m  =  400 / 300

m  =  4/3

Step 4 :  

Find the y-intercept.

Use the slope 4/3 and one of the ordered pairs (600, 750).

Slope-intercept form :  

y  =  mx + b

Plug m = 4/3,  x = 600 and y = 750.  

750  =  (4/3)(600) + b

750  =  (4)(200) + b

750  =  800 + b

-50  =  b

Step 5 :  

Substitute the slope and y-intercept.

Slope-intercept form

y  =  mx + b  

Plug m = 4/3 and b = -50

y  =  (4/3)x + (-50)

y  =  (4/3)x - 50

Graph the functions as transformations of f ( x ) = x
ivolga24 [154]
Since the functions are not included, I can help you with some examples and a  general explanations which will help you to solve this kind of problems.


1) Assumption: all the functions that are considered are linear.


That means that f(x) = x is the parent function, and you can obtain the other functions by a set of transformations (translation and scalation) of the parent function.

2) Example 1: y = x + a


This is a special case of adding a constant to the function.

In this case, the graph of the new function is the graph of the parent function shifted a units upward.

3) Example: y = 5x

This is a special case of multiplying the function times a constant.

The result is streching the graph vertically by the same scale factor.

4) Example: y = (1/5)x - 8

In this case, the graph of y is obtained by scaling the parent function f(x) = x by 1/5 (which results in compressing the parent function vertically) and shifting the parent function 8 units downward.

What is the sum or product of 9x52
solong [7]

Since this is a multiplication problem, we need to find the product. The product is 468. If you can't multiply, you can do 52 + 52 + 52 + 52 + 52 +52 + 52 + 52 + 52 and you still get 468.

Hope this Helps! :)
