To find the inverse of any function, switch the x's with y's and vice versa.


The current equation given is y=4x-8

Switch the y with x and switch the x with y


After doing so, we'll have the following equation:

x=4y-8


Now, let's move the variables around so that y is isolated on the left side again.


Subtract both sides by 4y


x-4y=-8


Subtract both sides by x


-4y=-8-x


Divide both sides by -4


y= \dfrac{x}{4}+2


That is the answer.

Have an awesome day!

10. Write a word problem for this equation:<br> n ($25) = $125
Andrei [34K]

Answer:

The word problem is "How many $25 are there in $125?"

<em></em>

Step-by-step explanation:

Given

n(\$25) = \$125

Required

Write a word problem for the expression

We start by solving the given equation

n(\$25) = \$125

Divide both sides by $25

\frac{n(\$25)}{\$25} = \frac{\$125}{\$25}

n = \frac{\$125}{\$25}

n = 5

This implies that there are 5, $25 in $125

<em>Hence; The word problem is "How many $25 are there in $125?"</em>
