Answer:
Solution of a System. In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system.
Cylinder and cone you use pi.

Answer:
After 4 days, the number of people attending both conferences be the same.
Step-by-step explanation:
We are given the following in the question:
Maths conference:
Number of people already signed = 7
Number of people who sign up each day = 2
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:
![f(x) = 7+2x](https://tex.z-dn.net/?f=f%28x%29%20%3D%207%2B2x)
History conference:
Number of people already signed =11
Number of people who sign up each day = 1
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:
![g(x) =11+x](https://tex.z-dn.net/?f=g%28x%29%20%3D11%2Bx)
Both conference will have same number of people when
![f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4](https://tex.z-dn.net/?f=f%28x%29%20%3D%20g%28x%29%5C%5C%5CRightarrow%207%20%2B%202x%20%3D%2011%2Bx%5C%5C%5CRightarrow%20x%20%3D%204)
Thus, after 4 days, the number of people attending both conferences be the same.
