39 dont forget the squared thigy
1) (solve for Y 1st)
-4y=16
y=-4
slope=0 y-inter= -4
2)(solve for X 1st)
6x=12
x=2
slope=undefined y-inter= none
Only the first one works
y = 3(-1)-2 = -5
y = -(0) -6 = -6 not -2
This is a substitution problem...
In order to solve, set up a proportion: 22/126=x/100. Cross multiply: 2200=126x. Divide by 126 on both sides: 17.46%=x
The answer is 3.5 + 1.5x = 12.5. So the answer would be C.
