Find the midpoint of the line segment with the given endpoints.<br> 1) (-8, 3), (-8,-4)
defon

Answer:

The answer is

<h2>( - 8 \: , \:  -  \frac{1}{2} )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-8, 3), (-8,-4)

The midpoint is

M = ( \frac{ - 8 - 8}{2}  \:   , \:  \frac{3 - 4}{2} ) \\    = ( -  \frac{16}{2}  \: , \:  -  \frac{1}{2} )

We have the final answer as

( - 8 \: , \:  -  \frac{1}{2} )

Hope this helps you

A board game that normally costs $30 is on sale for 25 percent off. What is the sale price of the game?
Roman55 [17]
25% off translates into 0.25($30) = $7.50 off.

A faster way to determine the sales price is to subtract 0.25 from 1.00 and then mult. the regular price by the result:  sales price = 0.75($30) = $22.50 (answer)
