Answer:
![\left\{\begin{array}{l}x+y\le 450\\7x+4y\le 1,150\end{array}\right.](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7Dx%2By%5Cle%20450%5C%5C7x%2B4y%5Cle%201%2C150%5Cend%7Barray%7D%5Cright.)
Step-by-step explanation:
Let x be the number of adults and y be the number of campers.
There are rooms for 450 people, so
x+y≤450.
Each adult costs $7, then x adults cost $7x.
Each camper costs $4, then y campers cost $4y.
There is a maximum budget of $1,150, so
7x+4y≤1,150
Hence, you get the system of two inequalities:
![\left\{\begin{array}{l}x+y\le 450\\7x+4y\le 1,150\end{array}\right.](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7Dx%2By%5Cle%20450%5C%5C7x%2B4y%5Cle%201%2C150%5Cend%7Barray%7D%5Cright.)
<u><em>x=-31.5 or x=-32.0 is the right answer. </em></u> First you had to multiply by -1.5 from both sides of equation. And it gave us,
. And finally simplify, and it gave us the answer is x=-31.5. You can also round up to the nearest tenths is x=-32.0. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Answer:
neither because A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.
