Question

How do you find an ordered pair to represent 1/2u-v given u=<-1,4> and v=<3,-2>?

Answer 1

`< -3 1/2, 4>`

Explanation:

If `u= <-1,4>`
then `1/2u= <-1/2,2 >`

and (if `v= < 3, -2>`)

then `1/2u-v =< -1/2, 2 > - <3, -2>`

`color(white)("XXX") = <-1/2-3, 2-(-2)>`

`color(white)("XXX") = <-3 1/2, 4>`
