Answer:
36
Step-by-step explanation:
12/2 = 6
= 36
It is a function because every input has exactly one output. It passes the vertical line test.
If you plotted another point at 2 hours it would no longer be a function bc 2 would be an input they had more than one output.
-np - 80 < 60....add 80 to both sides
-np < 80 + 60
-np < 140...divide both sides by p
-n < 140/p ...now multiply by -1 to make n positive, and change inequality sign
n > -140/p
