From any proportion, we get another proportion by inverting the extremes (or the means):
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
= -
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
or
(you can check this also by "the product of the extremes equals the product of the means")
3y = - 2x

Well, I'm drawing a blank here, but I know the series converges because it is a p-series and p, in this case is 7, is greater than 1, therefore converging.
Answer:
The scale factor is 4
Step-by-step explanation:
* Lets talk about dilation
- A dilation is a transformation that changes the size of a figure.
- It can become larger or smaller, but the shape of the
figure does not change.
- The scale factor, measures how much larger or smaller
the image will be
- If the scale factor greater than 1, then the image will be larger
- If the scale factor between 0 and 1, then the image will be smaller
* In the problem
- The vertex A of the triangle is (-6 , 4) and its image A' is (-24 , 16)
∵ -24 ÷ -6 = 4
∵ 16 ÷ 4 = 4
∴ The scale factor is 4
∵ 4 > 1
∴ The image of the triangle will be larger
* The scale factor is 4
