A21,000 gallon swimming pool contains 9000 gallons of water when a hose is placed into the pool and begins adding water at a rate of 1500 gallons per hour. use the segment tool to plot a graph representing the volume of water in the pool over time from when the hose is placed into the pool until it is full.

Step-by-step explanation:

We know that:

So, the pools needs 12,000 gallons more to be full. So, to solve the problem we could apply the rule of three. If 1500 gallons takes 1 hour, how much time would take 12,000 gallons:

So, using a linear model, it would take 8 hours to reach the maximum capacity of the swimming pool.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
