It's D. because you add the powers to get the solution. y x y + y x y = y x y x y x y = y^4
Answer: {3, 5, 7}

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input. The output values are y = 3, y = 3, y = 3, y = 5, y = 7. So we simply list these outputs without the "y=" portion. Toss out any duplicates. Only write the unique output values.
The curly braces surrounding the list of values tells us that we have a set.

Step-by-step explanation:
Answer:
x=-32
Step-by-step explanation:
expand -2(x+10): -2x-20
x-2x -20=12
add similar elements: x-2x=-x
x-20=12
add 20 to both sides
-x-20+20=12+20
simplify
-x=32
divide both sides by -1
x=-32
First factor the second fraction's denominator.
It is a difference of squares so it can be factored as (y + 4)(y - 4)
Notice the first fraction's denominator is y + 4. So you already have that.
Therefore the LCD is (y + 4)(y - 4) :)
