I need the graphs to help you, sorry ;_;
Lets say that Williams current age is x, since it is currently unknown
From here we know that in 15 years (x+15) he will be 3 times his age 5 years prior (3x-5). Thus we can set these equations up as equal to one another
1) x + 15 = 3(x - 5)
2) x + 15 = 3x-15
3) 30= 2x
4) 15 = x
5) Now this age is his current age of 15 years, but they also want his age 15 years from now
The equation is x + 15 = 3(x - 5)
This should be correct now, sorry for the misconception. Good luck
2u = <-2, 4>
-v = <-3, 2>
3w = <0, -6>
I just multiplied each vector by its scalar, then added the components.
answer: <-5, 0>
The third one is the answer
Answer:
I think the answer choices are incorrect. 7 1/2 in decimal form would be 7.5. Please correct me if I'm wrong.
