If segment EF has endpoints at E(-3,10) and F(5,6) and is dilated about the origin by a factor of 7 which of the following would be the length of its image, E'F'

  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).

is the anwser b. (-13)?

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

the answer for the question that you are asking is 4
