i need finding the second thing to the sequence. ( write this problem in recursive form)
im really bad at this kind of math so explain how you got the answer once you tell me said answer.

The green family is a family of six people. they have used 4,885.78 gallons of water so far this month. they cannot exceed 9,750.05 gallons per month during drought season. write an inequality to show how much water just one member of the family can use for the remainder of the month, assuming each family member uses the same amount of water every month.

Which inequality has a dashed boundary line when graphed ?

Evaluate the expression. (9 + 5)(3 + 2)0
