Vector u has its initial point at (15, 22) and its terminal point at (5, -4). Vector v points in a direction opposite that of u,
zzz [600]

Answer:

  D.  v=<20, 52>

Step-by-step explanation:

Vector u can be written in component form by subtracting its initial point from its terminal point:

  u = (5, -4) -(15, 22) = <-10, -26>

We are told that v = -2u, so ...

  v = -2<-10, -26> = <20, 52>

_____

Multiplying a vector by -1 reverses its direction; multiplying it by some factor k changes its magnitude by a factor of k. To reverse the direction and double the magnitude, we can multiply u by -2.

Y = -x + 3<br> y = x + 5
Gnom [1K]

Answer:

x = -1, y = 4.

Step-by-step explanation:

y = -x + 3

y = x + 5      Adding these 2 equation eliminates x:

2y = 0 + 8

y = 8/2 = 4.

Substituting for x in the first equation:

4 = -x + 3

4-3 = -x

1 = -x

x = -1.

The ratio of the side length of Square A to the side length of Square B is 4:9. The side length of Square A is 12 yards. What is
lubasha [3.4K]
A/B : 4/9 = 12/B
         cross multiply
         (4)(B) = (9)(12)
         4B = 108
         B = 108/4
         B = 27

P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B
