The first two steps in determining the solution set of the system of equations, y = x2 – 2x – 3 and y = –x 3, algebraically are
shown in the table. Which represents the solution(s) of this system of equations? A (3, 0) and (–2, 5)
B(–6, 9) and (1, 2)
C(–3, 6) and (2, 1)
D(6, –3) and (–1, 4)
Let the number be Y . Y is seven less than 5 times another (let that other be X) Y=7-5X sum of both Y and X minus 4 gives one Y+X-4=1 now solve both equations .
D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees.
