Answer:
(a-b, c)
Step-by-step explanation:
The midpoints of the two diagonals are the same, so we have ...
(P + (-a, 0))/2 = (O +(-b, c))/2
Multiplying by 2 and subtracting (-a, 0), we get ...
P = (0, 0) +(-b, c) -(-a, 0)
P = (a-b, c)
b is decreased by 25% which means there will be (-ve) sign.

- <em>Option 5 is correct!!~</em>
You just solve it like a normal multiplication problem and then start putting the decimal begin the answer and place it 3 numbers forward
