1. find the inverse function of y = -3x + 8
2. find the inverse function of y = 3/5x - 12

Question 1:

For this case we must find the inverse of the following function:

To do this we follow the steps below:

We exchange the variables:

We clear the value of the variable "y":

We change y for

The inverse of the given function is

Question 2:

For this case we must find the inverse of the following function:

To do this we follow the steps below:

We exchange the variables:

We clear the value of the variable "y":

We change y for:

ANswer:

The inverse of the given function is:

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

one that is bigger than 3 1/2
