(04.01 MC) If y = 9x − 7, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? (5 points) Select one: a. {(0, −7), (1, 2), (−1, −16)} b. {(−7, 0), (2, 1), (−16, −1)} c. {(1, 9), (2, 7), (3, 16)} d. {(7, 9), (8, 10), (9, 11)}

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: 5100 just subtract

step-by-step explanation:
