Answer:
![\left(\dfrac{7}{2},\ 1\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B7%7D%7B2%7D%2C%5C%201%5Cright%29)
Step-by-step explanation:
The formula of a midpoint:
![\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%5C%20%5Cdfrac%7By_1%2By_2%7D%7B2%7D%5Cright%29)
We have the points J(13, 8) and K(-6, -6).
Substitute:
![M_{JK}=\left(\dfrac{13+(-6)}{2},\ \dfrac{8+(-6)}{2}\right)=\left(\dfrac{7}{2},\ \dfrac{2}{2}\right)=\left(\dfrac{7}{2},\ 1\right)](https://tex.z-dn.net/?f=M_%7BJK%7D%3D%5Cleft%28%5Cdfrac%7B13%2B%28-6%29%7D%7B2%7D%2C%5C%20%5Cdfrac%7B8%2B%28-6%29%7D%7B2%7D%5Cright%29%3D%5Cleft%28%5Cdfrac%7B7%7D%7B2%7D%2C%5C%20%5Cdfrac%7B2%7D%7B2%7D%5Cright%29%3D%5Cleft%28%5Cdfrac%7B7%7D%7B2%7D%2C%5C%201%5Cright%29)
Since the 37 is negative the parabola will open downward.
The coefficient on the outside of the ^2 tells you if it opens up or down. If it's positive it opens upward and if it's negative it opens downward.
For the parabola to open sideways it would be a form of x = y^2
Answer:

C: 58
D: i dont know
E: 26
F: 58
Step-by-step explanation:
35/55=7/11 (i just divided by 5 in order to simplify)
