Answer:
D.
Step-by-step explanation:
In the first 3 equations, both sides are equal, so they each have infinitely many solutions.
The last choice is
3(-2x + 4) = -6x - 12
Distribute on the left side.
-6x + 12 = -6x - 12
Add 6x to both sides.
12 = -12
Since 12 = -12 is false, this equation has no solution.
Answer: D.
Answer:
29
Step-by-step explanation:
Since we know that the x-axis is 180 degrees and the square looking symbol represents that it is 90 degrees, we know that the other side has to also equal 90 degrees since 180-90=90.
To find the x, we need to subtract 90 from 61, which would give us 90-61 = 29.
Answer:
N is perpendicular to M
Step-by-step explanation:
Because N and P are parallel, p is perpendicular to M, N is also perpendicular to M
