Answer:

A

Step-by-step explanation:

v - 2u

= < - 2, 4 > - 2 < 2.5, - 4 > ← multiply each component by 2

= < - 2, 4 > - < 5, - 8 > ← subtract corresponding components

= < - 2 - 5, 4 + 8 > = < - 7, 12 >

Graph A shows the resulting vector

Answer: Graph A

Step-by-step explanation:

Hi, to answer this we have to solve the expression.

u = <2.5, -4>  

v= <-2,4>

v - 2u = <-2,4>- 2<2.5, -4>  

v - 2u = <-2,4>- <5, -8>  

v - 2u = <-7,12>

Correct option is A.

For the graph , we have to move 7 places to the left in the x axis (negative), go up in the y axis by 12 units, and connect that point with the (0,0).

Feel free to ask for more if needed or if you did not understand something.

The ____ of ____ property allows you to rewrite . xa· xb as xa + b.
gregori [183]
The rule of distributive property allows you to rewrite xa + xb as x (a + b).

So if x = 2, a = 3 and b = 4, xa + xb = x(a + b)
(2 * 3) + (2 * 4) = 2 (3 + 4)
6 + 8 = 14
14 = 14
...and so on. You may try it yourself with different variations.

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.
