Question 1206877: Please help me with this problem. Thank you.
Find the vectors u+v, u-v, and 5u-1/2. (Simplify your answers completely.)
u = i + j, v= -j-6k
u + v =
u - v =
5u- 1/2v=

u+=+i+%2B+j, v=+-j-6k

u+%2B+v+=+%28i%2Bj%29+%2B+%28-j-6k%29+=+i%2Bj-j-6k+=+i-6k

u+-+v+=+i+%2B+j-%28-j-6k%29+=+i%2Bj%2Bj%2B6k=i%2B2j%2B6k
