D is a function because there are no repeated x values
for example b is not a function because we have (0,-7) and (0,-9)
Answer:
A???
Step-by-step explanation:
i don't understand the question
but i feel like the question you just asked is 1-2 =
i hope this helped
(i doubt it did)
You can predict that it's odd because the end of the 2 numbers is 1 and 1 x 1 is 1 and one is an odd number. (answer is odd)
21*x=9*21
9*21=189
21*x=189
Divide 189 by 21 to solve for X or in this case "Blank"
189/21= 9
Midpoint = ( x1 + x2)/2, (y1+ y2)/2
Midpoint = (10 +6)/2, (6+10)/2
Midpoint = (8,8)
