Which set of ordered pairs represents a function? \{(-3, 7), (7, -3), (-7, 6), (-7, -1)\}{(−3,7),(7,−3),(−7,6),(−7,−1)} \{(7, -3), (-3, -9), (-3, -8), (8, 1)\}{(7,−3),(−3,−9),(−3,−8),(8,1)} \{(8, -9), (4, -8), (-4, 0), (-2, -8)\}{(8,−9),(4,−8),(−4,0),(−2,−8)} \{(-2, 8), (-3, -3), (1, -4), (1, 9)\}{(−2,8),(−3,−3),(1,−4),(1,9)}

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
