x = 20

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to the exterior angle

x + 2x+10 = 70

Combine like terms

3x+10 = 70

Subtract 10 from each side

3x+10-10 = 70-10

3x = 60

Divide each side by 3

3x/3 = 60/3

x = 20

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).
