Answer:
-3+10y
Step-by-step explanation:
Distribute the Negative.
The answer is b
2cos x + 1 = 0
2 cos x = -1
cos x = -1/2
x = cos^1(-1/2)
(cos inverse (-1/2))
x = 120°

Answer:
Neither
Step-by-step explanation:
Parallel must have the same slope.
Perpendicular must have reciprocal slopes.
These two contain neither.
So the slope formula is m= (y2-y1) /
(x2-x1). You can label -2 as x1 and 11 as y1. And the other point is x2 and y2. They you just plug it in the m= (y2-y1) /
(x2-x1) formula and solve. To get a better understanding look up, how to find the slope of a line with two points. Hope it helps
