Answer: a) r = 8 B) step two
<u>Step-by-step explanation:</u>
Step 1: -3(6 - r) = 6
Step 2: -18 + 3r = 6 This is where they made the error (-3 × -r = +3r)!
Step 3: 3r = 24
Step 4: r = 8
Answer:
r=8
Step-by-step explanation:
In the beginning you have to think about -3 x what = 6. It's -2. How can we get -2 from 6, we minus 8, so r = 8.
That also works in all the other equations if you want to try that out.

Answer:
The answer is b. 2,8 and 3,11
8=3(2)+2
8=6+2
8=8
11=3(3)+2
11=9+2
11=11
X=2 so 2+4=6 so y=6. I just gone ovee this unit aswell.
To find the side lengths, you have to factor 4x^2 + 28x + 49. This equation factored is (2x+7)(2x+7), so each side length is (2x+7) feet.
Answer:
x=-6
y=4
Step-by-step explanation:
x=-y-2 x=-y-2 x=-y-2 x=-y-2 x=-y-2 x=-4-2 x=-6
0.5x+y = 1 0.5(-y-2)+y=1 -0.5y-1+y=1 -y-2+2y=2 y=4 y=4 y=4
