Answer 1

Option B) - 2 u + w

Explanation:

Given that the vectors u and w in components are :

u = < 5 , - 5 > and w = < 4, - 9 >

then the operation ;

- 2 u + w gives:

- 2 < 5 , - 5 > + < 4, - 9 > = < - 10. 10 > + < 4, - 9 > =

= < - 10 + 4 , 10 - 9 > = < -6 , 1 > which are the components of the vector pictured in the image.
