Answer:
The domain of this function is first restricted to all non negative integers because the theater can sell only a whole number of tickets.
The domain is restricted to numbers less than or equal to 125 because the theater cannot sell more tickets than capacity.
Step-by-step explanation:
Answer:
{y,x}={441,45}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = x + 9
// Plug this in for variable y in equation [1]
[1] (x +9) - 9x = -1
[1] - 8x = -10
// Solve equation [1] for the variable x
[1] 8x = 10
[1] x = 5/4
// By now we know this much :
y = x+9
x = 5/4
// Use the x value to solve for y
y = (5/4)+9 = 41/4
Yes this is a function because there are no repeating x values.
