A Texas hotel has a number of conference rooms, c, available for events. Each conference room has
275 foldable chairs. Write an equation to represent f, the total number of foldable chairs, in all of
the conference rooms at the Texas hotel.

F = 275c

Step-by-step explanation:

Since f is the variable that is stated as necessary to find is should be a "stand alone". And because I know that every room has 275 chairs I can just multiply 275 by c to obtain the total number of chair in the hotel

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
