ANSWER

EXPLANATION
The given angle is 870°.
870°-360°-360°=150°
This means that:
870° is coterminal with 150°, hence its terminal side is in the second quadrant.
It makes an acute angle of 30° with the x-axis.
Note that cotangent is negative in the second quadrant,
Hence,

The first option is correct.
8.7 The absolute value just makes stuff positive.
Answer:
- 7/4
Step-by-step explanation:
y1 - y2 over x1 - x2 with the points (-3,4) and (1,-3)
-3 - 4 over 1 - (-3) --> -7/ 4
Answer:
A. g(x) = f(x - 6) + 2
Step-by-step explanation:
Vertex moves from:
(-6,-2) to (0,0)
g(x) = f(x - 6) + 2
