A cell phone plan charges $15 per month for unlimited call and text messages, however each gigabyte (GB) of data is charged at a rate of $7 per GB. Assume that fractional values of a GB are prorated according to this rate. If a user uses more than 12 GB of data during their monthly billing cycle, then they are not charged more than the cost for the first 12 GB. Write a piecewise-defined function that describes the amount a cell phone user will pay, C, as a function of the number of GB of data they use, d, over the course of a month.

d? maybe

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
