Answer:
y=1/2x-3
Step-by-step explanation:
First, let's put the line into slope intercept form
2y+4x=12
subtract 4x from both sides
2y=-4x+12
divide by 2
y=-2x+6
the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:
-2m=-1
divide by -2
m=1/2
so the slope of the perpendicular line is 1/2
here is the new line so far:
y=1/2x+b (b is a place holder)
now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation
1=1/2(8)+b
1=4+b
subtract 4 from both sides
-3=b
so the line is y=1/2x-3

Answer:
$25.30
Step-by-step explanation:
100% --- $22
100% + 15% --- ?
115% --- 
× $22 = $25.30
2(x+5)=8
2x+10=8
2x=-2
x=-1
