Answer:
Point B
-2 - 1/4 since it is going to the left of 0
X is the variable used in place of the building's height. I apologize if you can't read my hand writing very well.
Answer: 
Step-by-step explanation:
For it to bisect the segment, we need to find the midpoint.
The midpoint is 
Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.
The slope of the given segment is
, so the slope of the perpendicular bisector is 
Thus, the equation of the line in point-slope form is 
4x+7y=4.88 -> mult by -3 -> -12x-21y=-14.64
12x+8y=7.88
-12x-21y=-14.64
Add the two above equations together, the y will be left:
-13y=-6.76
y=0.52 —> cost of each apple (plug back into one of original equations, I chose 4x+7y=4.88:
4x+7(0.52)=4.88
Solve for x.
x=0.31 —> cost of each orange
