Answer:
x= -54
Step-by-step explanation:
distribution- -8x-36+3x=6-4x+12
add like terms- -5x-36=-4x+18
get x alone -5x=-4x+54. added 36 to both sides
add 4x to both sides -x=54
divide by -1. x= -54
Answer:
The slope is 3/5.
Step-by-step explanation:
I am assuming you mean
10x + 6y = 84
6y = -10x + 84
y = -5/3 x + 14.
So the slope of this line is -5/3 and the slope of a line perpendicular to it is
-1 / -5/3 = 3/5.
The answer is A. 3
