Is that your test or homework
Answer:
Step-by-step explanation:
2/3a + 2/5a - 3/4b - 7/4b + 12- 5
4/8a - 10/8b + 7
Solve for f(x) using both 4 and 8:
f(x) = 4+6 = 10
f(x) = 8+6 = 14
Find the difference between the answers:
The difference between the two answers is 14-10 = 4
Find the difference between the interval:
The difference between 4 and 8 is: 8-4 = 4
The rate of change is the change in the answers over the difference in the interval:
The rate of change is 4/4 = 1
