Question

How do you find an ordered pair to represent -8u given u=<-1,4> and v=<3,-2>?

Answer 1

`-8vecu = <8, -32>`

Explanation:

We're given two vectors

`vecu = <-1,4>`

`vecv = <3,-2>`

and asked to find the value of `-8vecu`, so vector `vecv` I'm assuming is irrelevant..

Vector `vecu` multiplied by the scalar quantity `-8` is thus

`<-8(-1), -8(4)>`

`= color(blue)(ulbar(|stackrel(" ")(" "<8, -32>" ")|)`
