Which statement explains how you could use coordinate geometry to prove that quadrilateral abcd is a rectangle? point a is at 5, 5. point b is at 7, 3. point c is at 3, 0. point d is at 1, 2.
urgent !

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
