Given vectors u= (1,-1,3) and v= (-4,5,3) find an ordered triple that represents vectors 3u-2v.

a.(16,1,-7)
b.(11,-13,3)
c.(10,-12,1)
d.(7,-7,16)

I don't want you to straight up give me the answer. I need someone to teach me how to solve this problem. I am home schooled and i cant figure this out.

  • Calculus - ,

    3 u = +3i - 3 j + 9k
    2 v = -8i + 10j + 6k
    -------------------- subtract
    1 x = 11i - 13j + 3k
    so I think b
