Answer:

the graph's slope-intercept is 3 or 3/1. you do this by finding the rise over run (how many squares does it go up, and how many does it go over).

The Y-intercept is -2. You can always find this by using the formula y= mx + b. Whatever number is in the place of "b" is the y-intercept.

I'm going to take a guess and say you're in Algebra 1. Either that or Pre-Algebra. This stuff took me a little while to full grasp, so don't worry! YOu'll understand it soon enough!

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. The drain pipe can be used to empty the pool in 34 ho
Talja [164]

<u>Answer: </u>

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs

<u>Solution: </u>

Let x = time it will take to fill the pool

\frac{1}{33} = work rate of inlet pipe

\frac{1}{34} = work rate of drain pipe

Using the formulae

Volume of flow=work rate \times time

Let us assume complete time of pool to fill = 1

Remaining fraction of pool to be filled = 1-\frac{1}{3}=\frac{2}{3}

\begin{array}{l}{\frac{1}{33} x-\frac{1}{34} x=\frac{2}{3}} \\\\ {\frac{x}{33}-\frac{x}{34}=\frac{2}{3}}\end{array}

\frac{34 x-33 x}{33 \times 34}=\frac{2}{3}

34 x-33 x=\frac{2 \times 34 \times 33}{3}

\begin{array}{l}{x=\frac{2244}{3}} \\\\ {x=\frac{3168}{3}} \\\\ {x=748}\end{array}

Time it will take to fill the pool = 748 hrs
