Algebraic notation is a method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the chessboard.
Hello,
6x+7iy=18-21i
==>
6x=18==>x=3
and
7y=-21==>y=-3
Answer A
Step-by-step explanation:
The equation of a parabola that relates it focus is

So here, we isolate x^2.


Next, we factor out 4.

Our p=8 so this tells us the distance of the vertex to the focus.
