Answer:
The other endpoint of the segment is
.
Step-by-step explanation:
The midpoint of the points
and
is given by the following formula:

where
= coordinates of the midpoint.
We know that the midpoint is (-15, 2) and an endpoint is (-12, 11). Substituting the information we have gives:

To find
we need to solve this equation:

and to find
we need to solve this equation:

The other endpoint of the segment is
.
Answer:
for the number 13
Step-by-step explanation:

by Pythagoras theorem
x= √81+36
x= √117
punch square root of 117 with a calculator, I don't have one now
Answer:
I dont understand the context of the question but something eqqual to that would be -6/8
Step-by-step explanation:
Slope intercept form y = -8x - 81
Point slope form (y - 7) = -8 (x + 11)
If I got it right it is 9.59166305.
