Question 183119
The previous solution is wrong you need to get the COMPONENT form for the vector u+v+w which means it's tail needs to be at the origin.

The work is right for the head of the vector but you need the tail as well which is at (0,-8), to recenter at the origin you need to add (0,8) to both the head and the tail so you would get...
Head = (-2,-3+8) = (-2,5) or -2i+5j
Tail = (0,-8+8) = (0,0)

And that's it. Cojelo con take it easy.
