Juan used algebraic properties to make an equivalent expression. He listed the properties in the order that he used them. Step Property Used 1 Associative 2 Distributive 3 Addition Which steps match the properties used? 15 + 7 n minus 8 + 3n = 7 n + 3 n + 15 minus 8 = (7 + 3) n + 15 minus 8 = 10 n + 7 12 n + 2 (4 n + 2) = 12 n + 8 n + 4 = (12 + 8) n + 9 = 20 n + 9 15 n + (17 n + 9) = (15 n + 7 n) + 9 = (15 + 7) n + 9 = 22 n + 9 12 n + 6 + 7 n = 12 n + 7 n + 6 = (12 + 7) n + 6 = 19 n + 16

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.
