Answer:
Y = 300 + 2X
Y( in dollars)
It is a functional relationship because a change in the value of X results in a corresponding change in the value of Y. And does not involve any uncertainty.
Step-by-step explanation:
Given:
Annual fixed due = $300
Variable cost = $2 per visit
X = number of visits in a year
Y = total yearly cost.
Y = annual cost + variable cost
Y = $300 + $2×X
Y = 300 + 2X
Y( in dollars)
It is a functional relationship because a change in the value of X results in a corresponding change in the value of Y. And does not involve any uncertainty.

Answer:
The answer is x < 8
Step-by-step explanation:
12x > 9(2x− 3) − 21
12x > 18x - 27 - 21
12x > 18x -48
12x - 18x > -48
-6x > -48
6x < 48
x < 48/6
x < 8
