Answer: 30×2n=C
Step-by-step explanation:
30$ is flat fee so no variable
2$ dollars per person so "n" (the number of people) is times 2
= the final cost (C)
Answer: x < 6

x < 6
Answer:y=0.096x+10.944
Step-by-step explanation:
I did the math
Answer: 
Step-by-step explanation:
To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.
First, you simplify the larger rectangle's area:
(x+10)×(2x+5) = 
Then, simplify the smaller rectangle's area:
(x+1)×(x+1) = 
Finally, subtract the smaller rectangle's area from the larger rectangle's area:

Therefore, the final answer is
.

Answer:
between x=-1.5 and x = 0
between x = 0 and x = 1.5
Step-by-step explanation:
For the interval -1.5 < x < 1.5, we can see that the slope is negative (i.e from top left to bottom right). Hence it can be said that the graph is decreasing during this interval.
For the other parts of the graph (as shown) the slope is positive (i.e from bottom left to top right). in those areas, the graph is increasing.
