One hose can nil a small swimming pool in 70 minutes. A larger hose can fill the pool in 55 minutes, How long will it take the two hoses to fill the pool working together?

x = 30.8 minutes

Step-by-step explanation:

Let x = time (mins) it takes for both

x(1/70 + 1/55) = 1

multiplying both sides by (70)(55):

x(55 + 70) = (70)(55)

x(125) = 3850

x = 30.8 minutes

OR

x = 30 minutes and 48 seconds

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
