Which of the following expressions has a value of 10. (a) (9+15) ÷3+2. (b) 9 +(15 ÷3 )+2. (c) 9 + 15 ÷ (3 + 2) (d) (9 + 15 ÷ 3) + 2. which one is it a b c d

step-by-step explanation:

  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).
