The coordinates of B will be "(2, -8)".
Given:
Midpoint of AB,
(x, y) = (0, -7)
Coordinates of A,
(x₁, y₁) = (-2, -6)
As we know,
The formula of midpoint is:
→
→
hence,
→
Thus the above answer is correct.

Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg.
Let the number of toys Oleg has = x
Let the number of toys Sasha has = y
Let the number of toys Dima has = z
Sasha had twice as many toys as Oleg
So y = 2*x= 2x
Dima had 40 more toys than Oleg.
z = x + 40
Oleg, Sasha, and Dima shared 600 toys
x + y + z= 600
We know y=2x and z=x+40
Replace it for y and z
Subtract 40 on both sides
Divide by 4 on both sides
Oleg had 140 toys
