You can substitute “y” back to check
Answer:
-2, (-5 is extraneous)
Step-by-step explanation:
assuming √(x+6) -4 =x
√(x+6) = x+4
square both side
x+6 = (x+4)^2
x+6 = x^2+8x+16
x^2+7x+10=0
(x+2)(x+5) = 0
x = -2, -5
put -5 back into org equation and it is not true
√(-5+6) -4 ≠ -5

Answer:
A: Quadrant IV
B. Quadrant III
Step-by-step explanation:
Quadrant IV is the bottom right
Quadrant III is the bottom left
Y = mx + b
Y = -6/5x + b
5 = -6/5(6) + b
5 = -7.2 + b
b = 12.2
Equation: y = -6/5 + 12.2
