Atanker truck fills the gas stations reservoirnat the rate of 12 1/2 gallons per minute if the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir

2.8 minutes

Step-by-step explanation:

Full volume / Refill rate = time elapsed in filling reservoir.

Thus:

elapsed time = 35 gallons / (12.5 gall/min) = 2.8 minutes

this is false ^.^ lol

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
