Question

6. Which of the following expressions is equivalent

to a negative integer?

A.5y+5/5y-5
B.6y-6/3-3y
C.2-2y/4y-4
D.8y-8/4y-4

Answer 1

B

Explanation:

B and D are the only answers that can be simplified into integers, and B is the only answer that is a negative integer.

to solve for
`(6y-6)/(3-3y)`, we pull out the like factors.

• 6y - 6 is equal to 6(y - 1)
• -3y+3 is equal to -3(y - 1)

cancel out (y - 1) on both sides.

your final result is -2.

Answer 2

Option C is equivalent to a negative integer when y is a positive integer:

2 - 2y / 4y - 4

= -2(y - 1) / 4(y - 1)

= -1/2

Therefore, the answer is C.
