Under a dilation, the point (-3, -4) is moved to (-15, -20).
what is the scale factor of the dilation

the answer is 4/3

Step-by-step explanation:

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

  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).
