Answer:
A. -8
Step-by-step explanation:
The average rate of change can be found with the formula
[f(b) - f(a)]/(b - a) on the interval a to b
Here, a = 3, b = 5, f(a) = -10, and f(b) = -26. Plug in the values and simplify...
[-26 - (-10)]/(5 - 3)
[-26 + 10]/2
-16/2
-8
It is a vertical line starting at 4 on x axis
Answer:
3 ( 5 + 7)
Step-by-step explanation:
15 and 21 both have the factor 3 in common so you can factor it out
Answer:
The value of 'a' is 4
Step-by-step explanation:
To find 'a', we just have to simplify and make 'a' the subject of

This gives us:

This implies that:

We divide both sides by 15 to get:
