Which relation is a function? (A) {(4, 2), (3, 3), (2, 4), (3, 2)}
(B){(1, 4), (2, 3), (3, 2), (4, 1)}
(C){(1, 2), (2, 3), (3, 2), (2, 1)}
(D){(1, −1), (−2, 2), (−1, 2), (1, −2)}

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

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
