Answer:

B(5, 4)

Step-by-step explanation:

The midpoint formula is ...

M = (A +B)/2

Solving for B gives ...

B = 2M -A

B = 2(1, -2) -(-3, -8) = (2+3, -4+8) = (5, 4)

The coordinates of B are (5, 4).

Step-by-step explanation:

$(2 \times 10) + (6 \times 1) + (9 \times \frac{1}{1000} ) \\ \\ =20 +6+ (9 \times 0.001 ) \\ \\ = 26 + 0.009 \\ \\ = 26.009$
