Jada walks up to a tank of water that can hold up to 20 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 12 gallons of water. Four minutes later, the tank contains 9 gallons of water. At what rate is the amount of water in the tank changing?
How many more minutes will it take for the tank to drain completely?
How many minutes before Jada arrived was the water tank completely full?

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
