I got 36
50% of 80 = 40
5% of 80= 4
40-4= 36
The midpoint formula is basically just the average of the two points. Here it is:

Then, you plug the points in. The answer is (-13,-5/2) or
C
Answer:
You get an perpendicular line through given point.
Step-by-step explanation:
In this method of drawing perpendicular line through given point,
you will draw an arc from given point R, so as to cut given line at A and B.
now ,length RA will be equal to length RB (radius of circle)
now, with length RA you will place compass at A and B to cut the arcs at point P (let) on other side of given line.Now, join PA and PB.
The closed RAPB makes a rhombus and diagonal bisect perpendicularly in rhombus.
so you get an perpendicular line through given point.
16x²-49=
(4x)²-7²=
(4x-7)(4x+7)
Here I have used the expression:
a²-b²=(a-b)(a+b)
