Answer: 
Step-by-step explanation:
The expression can be simplified by applying the a properties of exponents, specifically the Product of powers, which states that:
Where b is the base and a and c are exponents.
Then simplify it by rewriting the base (
) and adding the exponents of the expression (8 and 9).
You will get the expression simplified and written as a power:
It is (D) I believe. From what I can see it is going down from 1.40 to 1.39 from November to December which is a loss of 0.01
0.500 that what is the answer would be
59pounds * 5days = 295pounds
6.95pounds * 3breakfasts = 20.85pounds
12.50pounds * 1eveningmeal = 12.50pounds
295pounds + 20.85pounds + 12.50pounds = 328.35pounds
Wrote out the units just for clarity! Liz payed 328.25 pounds altogether.
Answer: f(12) = 137, f(-7) = 42
Step-by-step explanation: In a function, what you want to do is plug in the value they give you for x. This means you substitute x with the value they are looking for.
In this case, they are looking at 12 and -7. Let's do 12 first.
The equation becomes (12^2) - 7. 12^2 is 144, and 144-7 is 137.
Now we do -7. The equation becomes (-7)^2 - 7. -7^2 is 49, and 49 - 7 is 42.
Hope this helped!
