Question

Let u = <-5, 1>, v = <7, -4>. Find 9u - 6v.

Answer 1

Just multiply 9 to the components of u, and 6 to the components of v, and subtract the respective components

Answer 2

(Am I right to suppose it to be vectors)

Answer 3

wait i can no idea what your asking

Is it about vectors?

Answer 6

Let u = <-5, 1>, v = <7, -4>. Find 9u - 6v.

<18, 18>

<-87, 33>

<-36, -18>

<-3, -15>

Answer 7

umm let e check

Answer 8

yes it is

Answer 9

9u = <-5\(\times\)9, 1\(\times\)9> = <-45,9>
6v = <7\(\times\)6,-4\(\times\)6> = <42,-24>
Understand the above?

Answer 10

9u-6v = <-45-42,9-(-24)> = <-87,33>

Answer 11

you just saved me! thank you so much

Answer 12
