Question

Given u=(5,-2,3) and v=(1,1,2) find ordered triple that represents 3u-2v

Answer 1

Answer:

(13, -8, 5)

Step-by-step explanation:

Given

$u = (5,-2,3)\\and\\v = (1,1,2)$

We have to find 3u-2v

So,

$3u = 3(5,-2,3)\\3u= (15,-6,9)\\\\And\\\\2v= 2(1,1,2)\\2v= (2,2,4)\\\\3u-2v = (15,-6,9) - (2,2,4)\\= (15-2, -6-2 , 9-4)\\= (13, -8, 5)$

The ordered triple that represents 3u-2v is:

(13, -8, 5) ..
