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:
Yasmina:
5.25 x 5 = 26.25 per week
5.25 x 20 = 105 per month
5.25 x 260 = 1365 per year
Camila:
9.75 x 35 = $ 341.25 earnings per week
341.25 x 0.20 = 68.25 saves per week
9.75x35x 4= 1365 earnings per month
1365 x 0.20 = 273 saves per month
9.75 x 35 x 52 = 17745 earnings per year
17745 x 0.20 = 3549 saves per year
Your answer is 550000!!!
Hope this helped!!!XD
Also can I get brainiest?XD
we are given with 70 grams and is said that 48 grams is taken away. This is equal to 22 grams. To find the mass percentage, we divide the remaining mass and divide by the total mass. The remaining 22 grams is equal to 22/70 * 100 percent equal to 31.43 percent.
Which graph is the graph of this function?

if

So the graph is A.
Hope i've helped!
