Answer:
between 0 and 1
Step-by-step explanation:
The big key to this is that the negative sign in front of the two is NOT in parentheses along with the 2.
We follow the order of operations - PEMDAS - parentheses, exponents, multiplication and division, addition and subtraction.
So, inside the parentheses, the <u>first </u>thing we do is the <u>exponent</u>. We raise 2 to the third power and get 8.
Next, still inside the parentheses, we now multiply by negative 1. That is what putting a negative sign in front of something really is - multiplying by -1.
So now inside the parentheses, we have -8.
-8 raised to the power -2 is one over (-8) raised to the power positive 2.
That is one over 64,
That is more than zero, but less than one.
I have the math written out in an attached picture (I hate the equation writer on this website.) Haha.

Answer: A) Reflection along the line y = -1
===========================================================
Explanation:
Point A is at (1,5). Point A' is at (1,-7).
Apply the midpoint formula to find the center of these two points.
You should get (1,-1) as that midpoint.
Follow these steps for B(-1,3) and B'(-1,-5) to get the midpoint (-1,-1)
Those midpoints we found are located on the mirror line. We only need two such points to plot it. Drawing a line through (1,-1) and (-1,-1) graphs the equation y = -1. This is the horizontal line through -1 on the y axis.
