1. How could you figure out the coordinates of a reflection over the x-axis? What would the coordinates of that reflected point
be?
2. Then also tell how you could determine the coordinates when (-8,2) is reflected over the y-axis, and tell the coordinates of that new point.

Answer:
option (3) is correct.
Step-by-step explanation:
Given
We have to solve for e.
Consider the given statement,
Cross multiply, we get,
Taking square root both sides , we get,
We know square root of 9 is 3.
Thus, option (3) is correct.
From your equation, you can see that you have a difference of two cubes (aka two cubes being subtracted): 64, which is 
, and 
.
There is rule for the difference of two cubes:
The difference of two cubes is equal to the difference of the cube roots times a binomial, which is the sum of the squares of the roots plus the product of the roots.
That sounds pretty confusing, but it's much easier to understand when put mathematically. Let's say our two cubes are
and 
. The difference of those two cubes is:
In our problem, a = 4 (since = 64) and b = y (since 
. Plug these values into the rule to find the factor of
