Question

Find the results of the given vector subtractions for u = <-8, 4> and v = <2, 7>.

Answer 1

Explanation:

-u-v = 6,-11

u-v = -10,-3

v-u = 10,3

Answer 2

`\huge\boxed{\overrightarrow{u}-\overrightarrow{v}=\left<-10;\ -3\right>}`

Explanation:

`\overrightarrow{u}=\left<-8;\ 4\right>;\ \overrightarrow{v}=\left<2;\ 7\right>\\\\\overrightarrow{u}-\overrightarrow{v}=\left<-8;\ 4\right>-\left<2;\ 7\right>=\left<-8-2;\ 4-7\right>=\left<-10;\ -3\right>`
