Best ResponseYou've already chosen the best response.12*u you get if you multiply its coordinates by 2, 2*v also and than just substract them: first coordinate of u minus first coordinate of v and second minus second and you'll get that result

Best ResponseYou've already chosen the best response.1first you find the unit vector (vector which length is 1) in the direction of the given vector by formula \[u _{0}=u/\left u \right=(3,3)/\sqrt{(3^2+3^2)}=(1/\sqrt{2},1/\sqrt{2})\] ...than your vector is \[v=5\times(1/\sqrt{2},1/\sqrt{2})=(5/\sqrt{2},5/\sqrt{2})\]
