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.
