Answer:
$9.10
Step-by-step explanation:

455 ÷ 50 = 9.1. The student tickets cost $9.10. (I think)
The notation just means
(f/g)(-4) = f(-4) / g(-4)
If f(x) = x² + 2 and g(x) = 1 - 3x, then
f(-4) = (-4)² + 2 = 16 + 2 = 18
g(-4) = 1 - 3 (-4) = 1 + 12 = 13
and so
(f/g)(-4) = 18/13
Answer:
-5 5/10, -32/40,5
whenever a number has a negative sign,the larger the number the smaller.
i.e (-55/10= -5.5) is smaller than -32/40=-0.8 and then the greatest is 5 since it is a positive number and positive numbers are greater than negative numbers.
