Awater tank holds 549 gallons but is leaking at a rate of 4 gallons per week. a second water tank holds 732 gallons but is leaking at a rate of 7 gallons per week. after how many weeks will the amount of water in the two tanks be the same?

answer: 32.68

step-by-step explanation:

x=2

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
