Answer:
8x - 28y
Step-by-step explanation:
-2(-1x + 5y) + 3(2x - 6y)
2x - 10y + 6x - 18y
collect like terms
2x + 6x - 10y - 18y
8x - 28y
(-5, 12). Cosecant is the reciprocal of sine. Since csc theta =13/12, sin theta=12/13. We can narrow down to two angles, one in first quadrant and one in second quadrant. We are also given sec theta=-13/5, so cos theta=-5/13. Thus the angle is in the second quadrant. tan theta=1/cot theta=-12/5, so point (-5, 12) is on the ray.
