X= 7, -7 The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.
I combined the three steps together and the following are my thoughts:
We can set the fixed fee for renting as (f) and an dynamic fee related to days as (d) per day, then we have:
![\left \{ {{f+5d=36} \atop {f+8d=48}} \right.](https://tex.z-dn.net/?f=%20%5Cleft%20%5C%7B%20%7B%7Bf%2B5d%3D36%7D%20%5Catop%20%7Bf%2B8d%3D48%7D%7D%20%5Cright.%20)
Then we could get f=16, d=4, so we could have the equation as follows:
y = 16 + 4x

Step-by-step explanation:
In the diagram, P1P2 and Q1Q2 are the perpendicular bisectors of AB and BC, respectively. A1A2 and B1B2 are the angle bisectors of ∠A and ∠B, respectively <span>the center of the circumscribed circle of ΔABC is P </span><span>because both perpendicular bisectors go through the center
where they cross must be the center.</span><span>

10=0.25x+3
10-3=0.25x
7=0.25x
7/0.25=0.25x/0.25
28=x
Maximum number of games that can be played is 28.
