Which function has an inverse that is also a function? O {(-4, 3), (-2, 7), (–1, 0), (4, -3), (11, -7)} O {(-4, 6), (-2, 2), (–1, 6). (4, 2), (11, 2)} O {(-4, 5), (-2, 9), (-1, 8), (4, 8), (11, 4)} O {(-4,4), (-2, -1). (–1, 0), (4, 1), (11, 1)}​

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
