18. Look at the figure shown below.
2 units
B
Line segment AB is dilated by a scale factor of 2, with point C as the center of
dilation to obtain a line segment A'B'. If A'B' = 12 units, how many units is
point B' from point C?

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
