Which set of ordered pairs represents y as a function of x?
O{(1, 2), (2, 3), (3, 4), (3,5)}

{(2, 3), (3,5), (3, -5), (-2, 8), (-2, -8)

{(1,3), (1, 5), (1, 7), (1,9), (1, 11)}

{(1, 2), (2, -3), (3, 4), (4, -5)}

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

a ≈ 172.05
