Answer:
Option B) - 2 u + w
Step-by-step 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.
