A town’s water tower holds 1 million gallons of water. During the day,
the tower is only 2/5 of its full capacity. The tower will be refilled at night, when water
consumption is low, using a pump that pumps water into the tower at a rate of
2000 gallons of water per minute. How long will it take to bring the tower back to
full capacity? Explain how you got your answer. If the town had a pump that only
filled the tank at 500 gallons per minute, how much longer would it take to fill
the tank?

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation

x= -8
