:

a triangle has vertices of (-3,2), (1,-1), and (-3,-1). what are the vertices of the image produced by applying the translation (x, y) -> (x-5, y+2)?

a.
(–8, 4), (–4, 1), (–8, 1)
b.
(–5, 7), (–1, 4), (–5, 4)
c.
(2, 0), (6, –3), (2, 0)
d.
(2, 4), (6, 1), (2, 1)

A.  (–8, 4), (–4, 1), (–8, 1)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
