Given:
The graph of the system of inequalities.
To find:
The system of inequalities.
Solution:
From the given graph it is clear that the first line passes through the points (0,2) and (1,-1). So, the equation of the boundary line is:




The shaded region lies above the line and the boundary line is a solid line. So, the sign of inequality must by ≥.

The second line passes through the points (0,-2) and (3,0). So, the equation of the boundary line is:



The shaded region lies above the line and the boundary line is a solid line. So, the sign of inequality must by ≥.

Therefore, the system of inequalities contains two linear inequalities
and

Base on the question which ask to calculate Payton's Score if there is 1515 students, and the average of everyone's test is 8080 and Payton's average score is 8181, base on that, the total score of Payton is 161, 196. I hope you are satisfied with my answer and feel free to ask for more
Answer:
$3166.73
Step-by-step explanation:
If it measures 20 feet across, that means 10 feet will be the radius; furthermore, the height of 6 feet is given in the prompt. Now we can plug those in to the formula for the volume of a cylinder to find the capacity in cubic feet: πr² × h ≈ π × 10² × 6 = 600π. Now that we have the number of cubic feet of water it will take to fill the pool, we can just multiply that by 1.68 to find the cost, giving us $1008π, or $3166.73 if your teacher prefers that you don't answer in terms of π.
