When Reese opens the pipes to fill the pool she finds that only the slower pipe works. Write a rational equation that you can use to find how long it will take to fill the pool under these circumstances

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

is should be y = 5x
