Step-by-step explanation:
Answer:
Choice B
Step-by-step explanation:
Choice B is not a proportional relationship because it is not in the form of Y = KX.
First, you must convert the equation, X - Y = 2 to Y = MX + B by subtracting X to the right side to get -Y = -X +2. Then divide each side by -1 to get a positive Y value. Then you are left with Y = X - 2, which is not in the form of Y=KX.
We have been given an expression 
. We are asked to choose the expressions, which are equivalent to our given expression.
Using exponent property 
, we can rewrite our given expression as:
Upon looking at our given choices, we can see that option D is the correct choice.
Let us simplify our given expression.
Upon cancelling out 
from numerator and denominator, we will get:
Using exponent property , we will get:
Therefore, option B is a correct choice as well.
