Find the domain of the rational expression: 6-x/4x+20 A. All real numbers except 6
B. All real numbers except -20
C. All real numbers except -5
D. All real numbers except 0

B

Step-by-step explanation:

20

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
