Answer:
r=3
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
Distribute
3r -21 = 8 -8r +4
Combine like terms
3r -21 = 12 -8r
Add 8r to each side
3r +8r-21 = 12 -8r+8r
11r -21 = 12
Add 21 to each side
11r -21+21 =12+21
11r = 33
Divide each side by 11
11r/11 = 33/11
r = 3
The x intercepts the variable
Answer:
increase
Step-by-step explanation:
increase because it's going up
Sqrt 128 to get 11.31
You can do Pythagorean theorem. One side is 8, and since this is a square, the other side is 8. 8 squared plus 8 squared is 128, then square root it. Treat it like a right triangle
