Help...anybody know this??

-3

Step-by-step explanation:

1, -3, 9, -27, 81, -243

3⁰ = 1

(-3)¹ = -3

(-3)² = 9

(-3)³ = -27

(-3)⁴ = 81

(-3)⁵ = -243

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
