21. A triangle has vertices (1,5), (2,7), and (6,5). After a reflection and a translation, the
coordinates of the image are (5,-2), (6,-4), and (10,-2). Describe the transformation.
22.
Find the image of the point at (4, -7) under the translation along the vector (a, b).

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}
