The temperature, y, of a pot of water is 45 °F. The temperature increases by 30 °F per minute, x, when being heated.

y = 30x + 45

Step-by-step explanation:

The teapot starts of at 45 °F, and every minute, the temperature increases by 30 °F

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
