Determine if the equations are parallel, perpendicular, or neither. 1) x + y = 8 and y = -x - 1

2) 9x - 6y = -20 and -3y = 2x - 11

3) 2x = 14 + y and 4x + 2y = 10

4) y = -4 and y = 7

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30
