Answer:
Y=15x
Step-by-step explanation:
<h2>Okay so let's approach this problem!</h2><h2 />
X is books and Y is total cost
Let's find the slope!
Y2-Y1/ X2-X1
Just replace


The slope is 15

Now replace x and y with coordinates and solve

The final equation:
y = 15x

Let's solve this inequality!

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

Now, move 20 to the right, using the opposite operation:

Subtract:

Divide both sides by -1 to isolate x:
(Answer)
_____________
<em>Additional comment</em>
When we divide both sides of an inequality by a negative number, we flip the inequality sign.

Answer:
![f^{-1}(x)=\sqrt[3]{x}-6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7Bx%7D-6)
Step-by-step explanation:



![\sqrt[3]{x}=y+6](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%3Dy%2B6)
![\sqrt[3]{x}-6=y](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D-6%3Dy)

notice |7| 7 is positive, so we can simply remove the bars and use 7 by itself
