Question

Vectors :

if we have Ax=2cm and Ay=5cm
and Bx=4cm and By=-6cm

if A-B+2C=0 WHAT'S THE VALUES OF Cx AND Cy

is it Cx=1cm and Cy=5.5cm?

Answer 1

if A-B+2C=0
(ax,ay)-(bx,by)+2(cx,cy) =0
put them in this and find cx ,cy easily

Answer 2

So it's like I said ? since ax-bx=-2 and ay-by=11

Answer 3

so it's cx=1 and cy=-5.5

Answer 4

yes ,sure

Answer 5

thank u
