Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(-4,5), H(3,5), J(2, -1), and K(-5, -1).
The coordinates are

(1.5,1)

Step-by-step explanation:

The midpoint of G and H is at (2,2).

The midpoint if J and K is (1,0)

The midpoint of the two midpoints is (1.5,1)

You could also i.e. directly ask for the midpoint of H an K, OR, G and J, and you would get the same final result.

Step-by-step explanation:

BaF2 + Na2S = 2 NaF + BaS
