Question

I need help with question 5:) anything is appreciated:)))

Answer 1

`y=-150x+1600`

Explanation:

Linear Equation:

`$y=mx+b$`

`f(x)=mx+b`

Consider:

The pool is full when the time is zero:

`1600=m(0)+1600`

It is emptied (-) in the rate 150 gallons every hour.

`f(x)=-150x+b`

`f(x)=-150x+1600`

`y=-150x+1600`
