Find the midpoint of the line segment joining the points (-2,-2) and (-4,9).

11Alexandr11 [23.1K]

Answer:

The answer is

<h2> $( - 3 \: , \: \frac{7}{2} )$ </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

(-2,-2) and (-4,9).

The midpoint is

$M = ( \frac{ - 2 - 4}{2} \: , \: \frac{ - 2 + 9}{2} ) \\ = ( - \frac{6}{2} \: , \: \frac{7}{2} )$

We have the final answer as

$( - 3 \: , \: \frac{7}{2} )$

Hope this helps you

the larger of two number is 15 more than three times the smaller number. If the sum of the two numbers is 63, find tge numbers.

irakobra [83]

X is the smaller number. 3x + 15 is the larger number. So x + 3x + 15 = 63. 4x + 15 = 63.
4x = 48. x = 12. (Smaller number) The larger 36 + 15 or 51.
