11. let u = < -4, 1> , v = < -1, 6> . find -2u + 4v. (5 points)

The numbers in the <> are x and y values.

Replace u and v in the equation with their given values:

-2 <-4, 1> + 4<-1, 6>

Now multiply each number:

<8, -2> + <-4,24>

Now add the two x values and the 2 y values:

<4,22>

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
