Answer:
I would put B
Sorry if it's wrong I would have to know what the test is about to answer this
Step-by-step explanation:
Answer:
x=9
Step-by-step explanation:
Add similar elements: -5x+3x=-2x
-2x+15=-3
Subtract 15 from both sides
-2x + 15-15=-3-15
Simplify
-2x=-18
Divide both sides by -2
-21/-2 = -18/-2
Simplify
x=9
Angelica is 5 steps to the right while Brion is 12 steps to the left it is 17 steps because theyre going in the opposite directions :P

![\left|\dfrac{(-2)^n}{3^n+1}\right|=\dfrac{2^n}{3^n+1}](https://tex.z-dn.net/?f=%5Cleft%7C%5Cdfrac%7B%28-2%29%5En%7D%7B3%5En%2B1%7D%5Cright%7C%3D%5Cdfrac%7B2%5En%7D%7B3%5En%2B1%7D%3C%5Cdfrac%7B2%5En%7D%7B3%5En%7D%3D%5Cleft%28%5Cdfrac23%5Cright%29%5En)
As
![n\to\infty](https://tex.z-dn.net/?f=n%5Cto%5Cinfty)
, the sequence
![a_n=\left(\dfrac23\right)^n](https://tex.z-dn.net/?f=a_n%3D%5Cleft%28%5Cdfrac23%5Cright%29%5En)
converges to zero.
If you're talking about the infinite series
![\displaystyle\sum_{n\ge0}\dfrac{(-2)^n}{3^n+1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csum_%7Bn%5Cge0%7D%5Cdfrac%7B%28-2%29%5En%7D%7B3%5En%2B1%7D)
well we've shown by comparison that this series must also converge because we know any geometric series
![\sum\limits_n r^n](https://tex.z-dn.net/?f=%5Csum%5Climits_n%20r%5En)
will converge as long as
![|r|](https://tex.z-dn.net/?f=%7Cr%7C%3C1)
.
