For vector w is true: w = 2u-5v. Determine coordinates of vector w if u=(3, -1), v=(12, -10)

Correct result:

wx =  -54
wy =  48

#### Solution:

$w=2u-5v=\left(2\cdot 3+\left(-5\right)\cdot 12,2\cdot \left(-1\right)+\left(-5\right)\cdot \left(-10\right)\right)=\left(-54,48\right)$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
