√(x+7) = x + 1
Squaring on both sides,
x + 7 = (x + 1)²
x + 7 = x² + 2x + 1
x² + x - 6 = 0
x² + 3x - 2x - 6 = 0
x(x + 3) - 2(x + 3) = 0
(x - 2)(x + 3) = 0
x = 2 or -3
Hope this helps!
Answer:
2/3
Step-by-step explanation:
slope formula is ( y2 - y1 ) / ( x2 - x1)
so put in the values that are given to us
(5 - 3) / (-1-2)
= (2) / -3
= 2/3
Answer:
q= -10
Step-by-step explanation:
