The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. if g(x) is obtained by shifting f(x) down by 2 units, the value of k is

Step-by-step explanation:

The value of k is:

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
