Answer:

-6x - 2y = 12

Step-by-step explanation:

In graph, y = -6 when x = 0. So y-intercept is -6.

Now look at equations. You must divide the equation by the coefficient of y.

For example, look at the second one.

6x + 2y = 12

Divide by 2 (which is the coefficient of y)

Now equation is 3x + y = 6

Then rearrange it by subtracting 3x.

y = -3x + 6

Obviously this isn't the answer b/c the y-intercept here is 6, not -6.

Do the same for all.

The last one:

-6x - 2y = 12

-3x - y = 6

-y = 3x + 6

y = -3x - 6

This is the answer because the y-intercept is -6.

Which of the following geometric series converges?

Mars2501 [29]

All three series converge, so the answer is D.
The common ratios for each sequence are (I) -1/9, (II) -1/10, and (III) -1/3.
Consider a geometric sequence with the first term a and common ratio |r| < 1. Then the n-th partial sum (the sum of the first n terms) of the sequence is

Multiply both sides by r :

Subtract the latter sum from the first, which eliminates all but the first and last terms:

Solve for :

Then as gets arbitrarily large, the term will converge to 0, leaving us with

So the given series converge to
(I) -243/(1 + 1/9) = -2187/10
(II) -1.1/(1 + 1/10) = -1
(III) 27/(1 + 1/3) = 18
