Answer
a). vec(A)+vec(B)=$5.0x+3.0y$,
b). vec(B)-vec(A)=$-3.0x+7.0y$,
c). vec(C)=-vec(A)-vec(B)=-4.0x+2.0y-1.0x-5.0y=$-5.0x-3.0y$.
Work Step by Step
The 2 vectors are
vec(A)=4.0x-2.0y, vec(B)=1.0x+5.0y
a). vec(A)+vec(B)=5.0x+3.0y,
b). vec(B)-vec(A)=-3.0x+7.0y,
c). vec(C)=-vec(A)-vec(B)=-4.0x+2.0y-1.0x-5.0y=-5.0x-3.0y.
