Question

The rate of change ​

Answer 1

Answer:

All have a rate of change of 4.

Step-by-step explanation:

To simplify some things, we're going to be dividing by 10 because that's the separation between each answer. (40-50, 50-60, 60-70, yadda yadda yadda)

From 40 to 50 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 0 and 40 is 40.

From 50 to 60 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 40 and 80 is 40.

From 60 to 70 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 80 and 120 is 40.

From 70 to 80 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 120 and 160 is 40

From 80 to 90 we have a rate of change of 4, because 40 ÷ 10 = 4, we use 40 because the difference between 0 and 160 is 200
