Answer:
You can use the midpoint formula, knowing the midpoint between two points (x1,y1) and (x2,y2) has the coordinates
[(x1 + x2)/2, (y1 + y2)/2]
Substituting what we are given, we get:
(2 + x2)/2 = 5 and (5 + y2)/2 = 1
so,
2 + x2 = 10 and 5 + y2 = 2
Solving for x2 and y2 puts the endpoint at (8,-3), which is in the 4th quadrant.
You could also graph the points to get the same result.

Answer:
-27
Step-by-step explanation:
Any operations inside parentheses must be carried out first.
Thus,
9 ÷ 3[(20 − 7) − 22] becomes 9 ÷ 3[(13) − 22]
This, in turn, becomes 9 ÷ 3[-9].
The negative operator can be taken out and written up front: -9 ÷ 3[9) Note: this does not call for subtraction).
Carrying out the indicated operations from left to right:
-3(9) = -27
Answer:
2560
Step-by-step explanation:
39 x 115 = 4485
4997 - 4495 = 502
502/0.20 = 2560
