Jim is filling two pools at the community center. the first pool already contains 20 gallons of water and is being filled at the rate of 5 gallons per minute. the second pool already contains 50 gallons of water and is being filled at a rate of 3 gallons per minute. after how many minutes will the pools have the same amount of water?

15 minutes

Step-by-step explanation:

it would open into a square depending on the type of envelope i’m not sure about the second part

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
