What's the equation with a rate of change of 3 ​

1. 3y=2x+5
2.y=6x-3
3.y=3x+12

3. Y=3x+12

Explanation:

3 is used as the rate for whatever is for x

c

step-by-step explanation:

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
