The table shows Eric's work when solving the equation x - 8x - 65 0. Step Given Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Equation x2 - 8x - 65 = 0 x2 - 8x + 16 - 65 + 16 = 0 (x-4)2 - 49 = 0 (x - 4)2 = 49 x -4 = +7 x = 7+ 4 and x = -7 + 4 x = 11 and x = -3 In which step is Eric's work incorrect, and why?
1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need
