(40 points) a 21,000 gallon swimming pool contains 9,000 gallons of water when a hose is placed in 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 in the pool until the pool is full.(you can just tell me where to plot the points) (40 points)!

the answer is c. 23/3

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:

the answer is d   i just did this haha.
