Answer:
It's C.
Step-by-step explanation:
12x+4+9x+8=180
Combine like terms 21x+12=180
Subtract 12 from both sides 21x=168
Divide each side by 21 21x/21=168/21
x=8
z = 3.3
Given
2.2 = z - 1.1 ( add 1.1 to both sides )
3.3 = z
5 x y + 5 x + 4 y + 4
5x(y+1)+4(y+1)
(y+1)(5x+4)
The point-slope form:
We have the points (5, -3) and (-2, 9). Substitute:
