A water tank fills through two pipes. Water flows in through one pipe at a rate of 25,000 gallons per hour and in through the other pipe at a rate of 45,000 gallons per hour. Water leaves the system at a rate of 60,000 gallons per hour. There are 3 of these tanks, and each tank holds

1 million gallons. Each tank is half full. Water is entering and leaving a tank at the maximum amounts. Determine the number of hours, x, it will take to fill all 3 tanks one at a time.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
