Answer:

1/xy

Step-by-step explanation:

Simplify the numerator:

(2x - y)/(2x + y) + (2x + y)/(3y - 6x) + 8xy/(12x² - 3y²) =
(2x - y)/(2x + y) - (2x + y)/3(2x - y) + 8xy/3(2x + y)(2x - y) =
[3(2x - y)² - (2x + y)² + 8xy] / [3(2x + y)(2x - y)] =
[12x² - 12xy + 3y² - 4x² - 4xy - y² + 8xy] / [3(2x + y)(2x - y)] =
[8x² - 8xy + 2y²] / [3(2x + y)(2x - y)] =
2{2x - y)² / [3(2x + y)(2x - y)] =
2(2x - y) / [3(2x + y)]

Simplify the denominator:

(4x²y - 2xy²) / (6x + 3y) =
2xy(2x - y) / [3(2x + y)]

Now simplify the remainder of the expression:

2(2x - y) / [3(2x + y)] × [3(2x + y)]/[2xy(2x - y}] =
1/xy

Answer:

I think that the answer would be C because you have to multiply the term at the top. This would mean you would not do C. Sorry if this is wrong. At least you have your eliminating process now. lol so doing C is out of the box, which makes C your answer.

The relation is NOT a function.

Step-by-step explanation:

By definition:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component (domain/input/x value) and different second components (range/output/y value).

Looking at the given points in your graph, and in listing down the domain and range, we can infer that the relation is not a function because there is an x-value (2) that has two corresponding y-values: (2, 4) (2, 1).

Another way to tell if a given set of points in a graph represents a function by doing the "Vertical line test." The graph of an equation represents y as a function of x if and only if no vertical line intersects the graph more than once. Looking at the attached image, I drew a vertical line over points (2, 4) (2, 1). The vertical line intersects the two points, which fails the vertical line test. This is an indication that the given relation is not a function.
