Question

Given that OA= 11x +6y, OB=4x +10y and CO= - 13x+11y, write down each of the following vectors in its simplest form.

The following are
a) BA=
b) AC=

Answer 1

• BA = 7x -4y
• AC = 2x -17y

Explanation:

a) BA = OA -OB = (11x+6y) -(4x +10y)

BA = 7x -4y

__

b) AC = -CO -OA = -(-13x +11y) -(11x +6y)

AC = 2x -17y

_____

The vector OC is the opposite of the vector CO.
