Step-by-step explanation:

Assuming that the 270° rotation is in a clockwise motion,

A point (a, b) which undergoes such a rotation will have the new point (-b, a).

Since we have A(2, 1),

A' has the coordinates (-1, 2).

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

answer: the answer is e
