Y=-1/2x+3
y=-1/2x-5 is parallel:
y=-1/2x-1 is parallel: x+2y=-2
y=2x-4 is perpendicular: -2x+y=-4
y=1/2x+2 is parallel: -x+2y=2
Question 1:
(x*3)+18/8=9 is the equation
(x*3)+18=72 multiply by 8
(x*3)=54 Subtract 18
x=18 Divide by 3
The two digit number is 18
Question 2:
x*4=43 Divide by 4
x=10.75 10 3/4
10 3/4+3 3/4 Solve
