Apump removes 1500 gal of water from a pool at a constant rate of 40 gal/min. which equation models the amount of water y in the pool after t minutes?

y = 40t

Step-by-step explanation:

A pump removes 500 gallons of water at  a constant rate of 40 gallon/min.

∵ In one minute amount of water removed is 40 gallons.

∴ In t minutes amount of water will be removed = 40t

So equation will be y = 40t

y = 40t is the equation which models the amount of water y in the pool after t minutes.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
