9) Manny is 7 years older than David. Jeremy is 2 years younger than Manny. Their combined ages equals 102. How old are Manny, Jeremy and David?

Step-by-step explanation:

answer is done over here step by step

Manny: 37 years old

Jeremey: 35 years old

David: 30 years old

Step-by-step explanation:

First, we must divide 102 by 3, since there are 3 people in this scenario.

102 ÷ 3 = 34

We know that 34 is an estimate of each person's age, but there's still more work to do.

Manny is seven years older than David:

30 + 7 = 37

Jeremey is 2 years younger than Manny:

37 - 2 = 35

37 + 35 + 30 = 102

Hope this helps! :)

  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).
