That is not correct. I will help you. Begin by subtracting the 9x from both sides, like this: 9x - 9x + 2y = 6 - 9x. That simplifies to 2y = -9x + 6. Now divide both sides by 2 to get y all alone, like this:

. That reduces down to

. That is slope-intercept form. y = mx + b.
Answer:
The perimeter is 99
Step-by-step explanation:
you do 11x9=99
The expression 30 + 12 can be rewritten as 2x(13+8)
-2 is the correct answer.
