In a direct variation, y=20 when x=10. Write a direct variation equation that shows the relationship between x and y.

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

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
