9x + 3y = -22

3y = -9x - 22

y = -3x - 22/3
slope m=-3
lines are parrallel when m1=m2

m1=-3
<span> Y = -3x + 8
</span>m2=-3
s0 B is right option

9x + 3y = -22 |subtract 9x from both sides

3y = -9x - 22 |divide both sides by 3

y = -3x - 22/3

The line parallel to the line y = -3x - 22/3 has that same a slope.

Therefore your answer is B) y = -3x + 8.

Manolo says that the solution of the equation g squared equals 36 is g = 6 because 6*6 = 36. Is Manolos reasoning complete? Expl

Gre4nikov [31]

Answer: No. Manolo forgot to include that the opposite of squaring a number is square rooting. If you take the square root of 36, you get 6. When you square a number, you multiply it by itself, which is what Manolo did. He multiplied 6 by itself and got the answer of 36.

Step-by-step explanation: Hope this helps!
