Answer is 174.44
Answer: (1,16)
Step-by-step explanation:
The coordinates of a midpoint are given by the midpoint formula:
where
is the ordered pair for the midpoint,
is the ordered pair for the first endpoint, and
is the ordered pair for the second endpoint.
In this problem, the midpoint is given as ![(x_m,y_m) = (-3,7)](https://tex.z-dn.net/?f=%28x_m%2Cy_m%29%20%3D%20%28-3%2C7%29)
The known endpoint of XY is X = ![(x_1, y_1) = (-7, -2)](https://tex.z-dn.net/?f=%28x_1%2C%20y_1%29%20%3D%20%28-7%2C%20-2%29)
Y remains unknown so Y =
.
If the midpoint is given as (-3,7) we can compare the x value and the y value individually.
-3 = ![\frac{-7+x_2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-7%2Bx_2%7D%7B2%7D)
Solving for
, we get
= 1.
7 = ![\frac{-2+y_2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%2By_2%7D%7B2%7D)
Solving for
, we get
= 16.
Thus, the coordinates of Y are (1,16)
Answer:
Using point-slope formula, if you're trying to find a parallel or perpendicular line to it.
Step-by-step explanation:
The answer is b because 60% is not in the word problem, so you could've used process of elimination to get rid of choice a.
