Select the correct function.
select the function with an average rate of change of -6 over the interval [2, 4].

Check the picture below.

so let's use those two points the line passes through to get its slope.

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)(x-2)^2+(y-1)^2=9

step-by-step explanation:
