Answer:
Over
Step-by-step explanation:
Answer:
x = 27
Step-by-step explanation:
x/9 = 3
Multiply each side by 9
x/9 * 9 = 3*9
x = 27
Rearrange the equation by writing
x² + x - 90 = 0
x² + x = 90
x² + x + 1/4 = 90 + 1/4
Recall that (a + b)² = a² + 2ab + b². Then
x² + 2 • x/2 + (1/2)² = 361/4
(x + 1/2)² = 361/4
x + 1/2 = ± √(361/4)
x = -1/2 ± 19/2
x = 9 or x = -10
answer = not define
Step-by-step explanation:
slope = (y2- y1) / (x2- x1)
= 9-3 / 7-7
= 6/0
= not define
