The numerator represents a number of equal parts, and the denominator is how many of those equal parts make up a whole.
Answer:

Step-by-step explanation:
product is the result of multiplication which means multiplication is involved with 2 and a number which can be substituted for x
5 is subtracted from all of that
7 is the answer of it all
Answer:
B. -3 1/2y + 2
Step-by-step explanation:
Our expression is:
.
Let's first distribute out that parentheses. Remember that distribution is simply taking the sum of the product of the outside term with each of the inside terms. Here, the outside term is 1/2 and the inside terms are 4 and -2y:

Now, we have:

We want to combine like terms, which means combining all the terms with y in them:

Remember that -7/2 can be written as the mixed number -3 1/2, so our final answer is:
-3 1/2y + 2
The answer is thus B.

Answer:
2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 2, 4 ] , then
f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12
f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0
Then
average rate of change =
=
= 2
