What is the inverse of the given relation y = 4x - 8
Ronch [10]

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!

An inlet pipe on a swimming pool can be used to fill the pool in 38 hours. The drain pipe can be used to empty the pool in 40 ho
AlexFokin [52]

To solve this problem you must apply the proccedure shown below:

1. In a hour you have \frac{1}{38} of the pool filled and \frac{1}{40}.Taking \frac{1}{4} of the pool filled, you have the following expression:

\frac{1}{38}-\frac{1}{40}=\frac{1}{4}/t

2. Solve for t, as following:

t=\frac{760}{4}\\ t=190 hours

The answer is: 190 hours
