Answer:

Step-by-step explanation:

It's the most logical of them all, it can't be A, it wouldn't make sense if it's C, and for D it says 6 if -5<x<u><</u>-1 and it has the little line on 6 for y, it sounds a little complicated but that's my logic

Determine whether the pair of equations represent parallel lines, perpendicular lines, or neither.

Ivahew [28]

Answer:

Parallel

Step-by-step explanation:

Parallel lines have the same slope but different y-intercepts. If you multiply the top equation by 2, you get:

2(12x + 4y = 16)

24x + 8y = 32

This shows that both lines have the same slope, but then you find the y-intercepts, they are different:

1st equation y-int = 4

2nd equation y-int = 9/2 or 4.5
