Im tired Which of these describes a ray?

Question 3 options:

Extends in both directions with no end

A part of a line that connects two endpoints

Has a start point but no endpoint

An exact location that has position but no size

I would say B. not to sure tho

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
