Study the diagram of circle C, where two chords, AB and DE, are equidistant from the center.

If AB=3x−7, and DE=5(x−5), what is the length of AB?

  20 units

Step-by-step explanation:

Chords the same distance from the center have the same length, so ...

  AB = DE

  3x -7 = 5(x -5)

  3x -7 = 5x -25 . . . . . eliminate parentheses

  18 = 2x . . . . . . . . . . . add 25-3x

  9 = x . . . . . . . . . . . . . divide by 2

AB = 3x -7 = 3(9) -7 = 20

The length of AB is 20 units.

"image"

step-by-step explanation:

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.
