@SolomonZelman

Answer 1

I hope this is not about vectors :)

Answer 2

i only have like 3 more problems left that i need help in

Answer 3

oh noo is vectors bad?

Answer 4

u ≤ -5
v ≤ -6

this is the given?

Answer 5

Yes, vectors are very bad. I am a trig student, and the only think I didn't understand from calc1 book was this section about vectors.

Answer 6

only *thing

Answer 7

hahaha thats okay, but thanks for the help with everything else (:

Answer 8

\[
-3\mathbf u = -3\langle -5,-3\rangle = \langle -5\cdot -3,-3\cdot -3\rangle = \langle 15,9\rangle
\]

Answer 9

Do the same to find \(5\mathbf v\).

Answer 10

Ok

Answer 11

5(-6,-1)= (-30,-5)

Answer 12

i am right> @wio ??

Answer 13

<-15, 4>

Answer 14

That is the correct <v> yes

so now

<15 , 9> + <-30 , -5> = <15 - 30, 9 - 5> = Yes <-15 , 4>
