X=0 bexause the 3s cancel out and your left with 2x=0 so x=0

So what you want to do is make it so all the X's are on one side, and all the numbers on the other.

Basically, making it so like terms are on the same sides.

So basically:

x+3+2x=x+3

What you can first do is:

x + 2x + 3 = x + 3

3x + 3 = x + 3

And then you could:

3x + 3 - 3 = x + 3 - 3

3x = 0

/3     /3

x = 0

Which geometric series converges?
kvv77 [185]

Answer:

Option (1)

Step-by-step explanation:

In a geometric series,

\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....

Here r = \frac{a_n}{a_{n-1}}

For |r| < 1, series will converge.

For |r| > 1, series will diverge.

Option (1)

Given geometric series is,

\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......

Common ratio = \frac{\frac{1}{4}}{\frac{1}{2} }

                        = \frac{1}{2}

Since, \frac{1}{2}

Series will converge.

Option (2)

\frac{1}{2}+1+2+4+......

r = \frac{1}{\frac{1}{2}}=2

Since, 2 > 1,

Series will diverge.

Option (3)

\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......

Common ratio 'r' = \frac{\frac{3}{2} }{\frac{1}{2} }=3

Since, 3 > 1,

Series will diverge.

Option (4)

\frac{1}{2}+3+18+108+.....

Common ratio 'r' = \frac{3}{\frac{1}{2}}=6

Since, 6 > 1

Series will diverge.

Therefore, Option (1) will be the correct option.

Y &amp; X vary directly if the constant of variation is 4 then what is the value of x when y equals 6
shepuryov [24]
I think that x would be 1.5.
6 = 4x, 6/4 = 1.5, so 1/5 = x
