Given the vectors u = <5,-1> and v = <1,12>, find -7u-3v. *
zepelin [54]

You multiply vectors and scalar simply by multiplying each component by that scalar:

-7u = \langle-35,7\rangle,\quad -3v=\langle -3,-36\rangle

Finally, you sum two vectors by summing the correspondent coordinates:

-7u-3v = \langle-35,7\rangle+\langle -3,-36\rangle = \langle-38,-29\rangle
