Answer:
f(x) - when referring to a function - means that x is the input value that you substitute into an equation.
For example, if f(x) = 2x + 3 and you were asked to find f(2), you could substitute x = 2 into the equation 2x + 3 to get 7.

Answer:
y = 6 when x = 18
Step-by-step explanation:
The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.
We know y = 3 when x = 9: 3 = k(9)
This yields k = 3/9, or k = 1/3
Then the formula is y = (1/3)x
and when x = 18, y = (1/3)(18) = 6
y = 6 when x = 18

Step-by-step explanation:
Distance traveled by an airplane in 7 hours = 4,914 kilometers
We have to determine the unit rate for kilometers per hour.
So, distance traveled by an airplane in 1 hour =
= 702 kilometers.
So, an airplane will travel 702 kilometers in an hour.
Therefore, the unit rate for kilometers per hour is 702 km per hour.
