Find the inverse function
y=-5x+20

Step-by-step explanation:

The inverse function is a function that reverse a given function.

You can follow this procedure:

The given equation is

First change the position of the x, because is the variable you need.

Now substract 20 in both sides of the equation:

Do the necesary calculations

Now divide by -5 both sides of the equation to clear X

simplify:

Finally you will get:

y=x+9
