Using the together rate, it is found that it would take them 16 hours to sew 12 dresses.
<h3>What is the together rate?</h3>The together rate is the <u>sum of each separate rate</u>.
In this problem, we have that:
- Vera's rate is of 1/2.
- Ivy's rate is of 1/4.
Hence, the together rate is the time it would take them to produce one dress working together, and is given by:
Then one dress takes of an hour, and the time for twelve dresses is:
It would take them 16 hours to sew 12 dresses.

Explanation:
The scale factor is 2, which means we double each coordinate of each point. The general rule is with k = 2. So we can say the more specific dilation rule is
Something like W(-2,2) moves to W ' (-4, 4) after multiplying each coordinate by 2. Do the same for the other points as well.
The given preimage points
- V = (-2, -1)
- W = (-2, 2)
- X = (0, 2)
- Y = (3, -1)
will dilate to the corresponding image points
- V ' = (-4, -2)
- W ' = (-4, 4)
- X ' = (0, 4)
- Y ' = (6, -2)
as shown below. This causes the image to be larger compared to the preimage (since the scale factor is larger than 1). Any given point is twice as far from the origin as compared to before, which in turn means the distance between any two points is twice as much.
