1. m2 = 122° andm3 = 58° Second Substitution
2. 3 and 5 are supplementary angles
Exterior Sides in Opposite Rays
3. m3 + m5 = 180°
Given
4. 58° + m5 = 180°
If corresponding angles are equal, then lines are parallel.
5. m5 = 122°

  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).

x/3-10=8

x/3=18

x=48

step-by-step explanation:

hope this !
