For the universal set, U={5, 6, 7, 8, 9), complete the parts below. Write your answers in roster form or as Ø.
A' =
X Х
(a) Suppose A = {5, 8, 9). Then what is A'?
0
(b) Suppose we know that C'={5, 6, 9). Then what would have to be?
C = ]

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
