I NEED HELP WITH MATH HOMEWORK PLEASE.

Step-by-step explanation:

we know  A + B + C = 180 for a triangle

isosceles have the same angles on the base sides

so our equation can be rewritten with that

A + A + C = 180

2A+C=180

so we are also told that A is 9 less than 4 times the vertex .. vertex is the point or top... in this case.. or C

A= 4C-9

now plug it in

2(4*C-9) + C =180

8C-18+C=180

9C-18=180

9C=198

C = 22

  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).
