Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
Answer:
Step-by-step explanation:
The answer is $72
because if you subtract the discount by 96 you get 72
This is a percent problem which means
You take the amount that has been completed over the total amount. You then multiply it by 100%
30/120*100=25%
