Solve for x and y

Already solved for x if you can please go over it and correct me if wrong

x = 28

y = 83

Step-by-step explanation:

We can use ratios to solve

18           21

 =

24            x

Using cross products

18x = 24*21

Divide each side by 18

x = 24*21/18

x =28

The angles must be equal

<M = <I

83 = y

  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).

i can answer this question sweetie!
