7. Describe the trend you see in the data in the context of the situation. 8. Draw a line of best fit and write an equation that matches it (you'll need the slope and y-intercept).
9. Use your line of best fit to predict the price of a car that is 10 years old.
10. Which variable is the dependent variable? Explain...

f-1(x)= cube root of 19x squared/x

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
