Answer:
This construction shows how to draw the perpendicular bisector of a given line segment with compass and straightedge or ruler. This both bisects the segment (divides it into two equal parts, and is perpendicular to it. It finds the midpoint of the given line segment.
The answer is $856.70 because if her bank account was negative you add the negative balance to the current balance of $822.98
Step-by-step explanation:
There are many possible solutions. For example:
3x + 0 = 1x + 4
4x + 1 = 2x + 5
5x + 2 = 3x + 6
I might just give two of them.
28. y=45°,
13x13=169
169/2=84.5
√84.5=x
x=2√21+√2/2
31. (5√2)²=50
50/2=25
x=√25=5
(5√2)²+(5√2)²=100
y=√100=10
Those are your answer.
