How to solve x + 2y = 13
4x + 8y = −9
i get confused after eliminating the x.
?

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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
