In the expression [Image Displayed] what is k? a.
inverse variation
c.
constant of variation
b.
direct variation
d.
the solution

the answer is A

Step-by-step explanation:

this this is because a is inversely proportional to b so therefore k becomes an inverse variation

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
