Answer:
C. 12
Step-by-step explanation:
Average rate of change = 
Where,
a = 1, f(a) = 3
b = 3, f(b) = 27
Average rate of change = 
Average rate of change = 
Average rate of change for the interval from x = 1 to x = 3 is 12
Answer: x = 8
Step-by-step explanation: 1/4(x+12)=5 is the same as 1/4x + 3 = 5. 1/4 of 8 is 2. 2+3=5.
Answer:
Erm idk what you meant but the answers either 0.8 or .125
Hope this helped!
Good luck :p

Answer:
-6x+12
-9+5a
7x+63
8y-4/5x-12
Step-by-step explanation:
To solve these all you have to do is take the number outside of the parenthesis and multiply them by each term.
-3(2x)-3(-4) All I did here was expand the problem to show what i mean by terms.
-6x+12
Do this for each problem.
0.1(-90)+0.1(50a)
-9+5a
-7(-x)-7(-9) For this one you are taking negatives times negatives so each answer will be positive.
7x+63
4/5(10y)+4/5(-x)+4/5(-15)
8y-4/5x-12
Answer: the slope would be a negative slope with -15 as the y intercept.
