Answer 2

u has components of 5, and 6.
-2u would multiply them by -2, so the new components of u is <5*-2,6*-2> = <-10,-12>

Same idea for v.
Then once you have 2 sets, add the x-variable together, and the y-variable together like:
u = <a,b>
v = <c,d>
u + v = <a+c,b+d>

Answer 3

so it would be 0, 18

Answer 4

v = <-2, -6>

5*v = 5*<-2, -6>

5v = <5*(-2), 5*(-6)>

5v = ???

Answer 5

@jim_thompson5910 18

Answer 6

you should get a vector

Answer 7

0,18

Answer 8

Answer 9

for now I'm only focused on `<5*(-2), 5*(-6)>`

Answer 10

10 and -30

Answer 11

you're close but one value is incorrect

Answer 12

-10

Answer 13

<5*(-2), 5*(-6)> = <-10, -30>

Answer 14

-2u + 5v = -2<5,6> + 5<-2,-6>
-2u + 5v = <-10,-12> + <-10, -30>

add up the corresponding coordinates

Answer 15

yes

Answer 16

what would <-10,-12> + <-10, -30> simplify to?
