Question

Let u = <-9, 4>, v = <8, -5>. Find u - v.

Answer 1

-17

Explanation:

-9-8

Answer 2

Answer:
`u-v=<-17,9>`

Explanation:

In order to subtract two vectors:

`u=<u_1,u_2>` and
`v=<v_1,v_2>`

It is necessary to subtract the corresponding components:

`u-v=<u_1-v_1,u_2-v_2>`

Then, given the vectors:

`u = <-9, 4>` and
`v = <8, -5>`

We know that
`u-v` is:

`u-v=<-9-8,4-(-5)>`

`u-v=<-17,9>`
