Welcome to Brainly!

This problem is odd in that no information is given regarding the relationship, if any, between x and y, and (more importantly) x can't have both values -15 and 21. Please go back and ensure that you have copied down this problem precisely as it was given you.

-8x - 46 = -6x - 8
-8x + 6x = -8 + 46
-2x = 38
x = -19

The equation:
-8x - 46 = -6x - 8

The solution:
x = -19

Find the midpoint of the segment with the given endpoints. (9,9) and (6,8)

mars1129 [50]

<u>Answer:</u>

The mid-point is (7.5, 8.5).

<u>Step-by-step explanation:</u>

We are given two points (9,9) and (6,8) as the endpoints for a line segment and we are to find the midpoint of this segment.

We know that the formula for finding the mid point is:

<em>Mid point = $(\frac {x_1 + x_1 }{ 2 } ,\frac { y_1 + y_2} {2} )$ </em>

So substituting the given values of the coordinates of the endpoints in the above formula to get:

$= (\frac {9 + 6}{2} , \frac {9 + 8}{2} )$

$= (\frac {15}{2} , \frac {17} {2} )$

$=(7.5, 8.5)$

Therefore, the mid-point is (7.5, 8.5).
