Answer 1

Let u = <5, 6>, v = <-2, -6>. Find -2u + 5v. (1 point)

<-20, -42>
<-20, 0>
<0, 18>
<-6, 0>

Answer 2

to evaluate the range for -2u+5v, you simply substitute the ranges for u and v in the eqn...

Answer 3

in this case u <5,6> and v <-2,-6>

Answer 4

I have no idea...

Answer 5

Answer 6

the expression is -2u+5v ok?

u is in between 5 and 6 and v is between -2 and -6

so far so good?

Answer 7

yes

Answer 8

@sdfgsdfgs

Answer 9

to find the range, we need to find the smallest and largest possible value for -2u+5v

Answer 10

okay!

Answer 11

u is in between 5 and 6; which will give the smallest -2u and will give the largest -2u?

Answer 12

5

Answer 13

@sdfgsdfgs

Answer 14

I think u and v are vectors here

Answer 15

Wait. I think I got is. Dilate coordinates u by -2 so that would be (10,12). Dilate v by 5 so that would be (-10,-30). now add so you get (0,-18)

Answer 16

@Plasmataco, you have the right idea but you have sign error
