Answer:
S(7, -37)
Step-by-step explanation:
Let the coordinates of point S be (x, y).
(14 + x)/2 = 7
14 + x = 14
x = 0
(21 + y)/2 = -8
21 + y = -16
y = -37
Answer:
Step-by-step explanation:
![\displaystyle -9[5] + 3[7] + 4 = -45 + 21 + 4 = -20](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-9%5B5%5D%20%2B%203%5B7%5D%20%2B%204%20%3D%20-45%20%2B%2021%20%2B%204%20%3D%20-20)
