choose you as a Trusted HelperBeing a moderator means helping in many ways that most people can't. It's nice to be a leader. As a moderator, you get a sense of authority; other users look up to you to help guide the site. This can be surprisingly appealing
Answer:
all real numbers less than or equal to –3
Step-by-step explanation:
Look at the y-values that the graph shows. There are none greater than -3. Any value of -3 or less is possible.
Answer:
it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

Answer: Option C
![AC = 2\pi](https://tex.z-dn.net/?f=AC%20%3D%202%5Cpi)
Step-by-step explanation:
The arc length is calculated as
![L = \theta * R](https://tex.z-dn.net/?f=L%20%3D%20%5Ctheta%20%2A%20R)
Then
![AC = \theta * R](https://tex.z-dn.net/?f=AC%20%3D%20%5Ctheta%20%2A%20R)
We know that
![BC = 24\ ft](https://tex.z-dn.net/?f=BC%20%3D%2024%5C%20ft)
If BC is the diameter of the circumference then the radius R is:
![R = \frac{BC}{2}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7BBC%7D%7B2%7D)
![R = \frac{24}{2}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7B24%7D%7B2%7D)
![R = 12\ ft](https://tex.z-dn.net/?f=R%20%3D%2012%5C%20ft)
Now we convert the anglo from degrees to radians![\theta= 30\° * \frac{\pi}{180\°}\\\\\theta=\frac{1}{6}\pi](https://tex.z-dn.net/?f=%5Ctheta%3D%2030%5C%C2%B0%20%2A%20%5Cfrac%7B%5Cpi%7D%7B180%5C%C2%B0%7D%5C%5C%5C%5C%5Ctheta%3D%5Cfrac%7B1%7D%7B6%7D%5Cpi)
Finally
![AC = \frac{1}{6}\pi * 12](https://tex.z-dn.net/?f=AC%20%3D%20%5Cfrac%7B1%7D%7B6%7D%5Cpi%20%2A%2012)
![AC = 2\pi](https://tex.z-dn.net/?f=AC%20%3D%202%5Cpi)
