Option E
The numerator of fraction is 21
<h3><u>Solution:</u></h3>
is to be written as improper fraction in lowest terms
To find: numerator of fraction
An improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number).
<em><u>To convert a mixed fraction to an improper fraction, follow these steps:</u></em>
- Multiply the whole number part by the fraction's denominator.
- Add that to the numerator.
- Then write the result on top of the denominator.

Thus the numerator of fraction is 21. Option E is correct
Answer:
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is: 
Step-by-step explanation:
Given points are:
(-5,3) and (3,7)
The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.
First of all we have to find the slope and mid-point of given line
Here
(x1,y1) = (-5,3)
(x2,y2) = (3,7)
The slope will be:

The mid-point will be:

Let m1 be the slope of the perpendicular bisector
Then using, "Product of slopes of perpendicular lines is -1"

We have to find the equation of a line with slope -2 and passing through (-1,5)
The slope-intercept form is given by:

Putting the point (-1,5) in the equation

The final equation is:

Hence,
The equation of perpendicular bisector of the line segment passing through (-5,3) and (3,7) is:
