(f, c) Gale thought that it would be fun to go to the carnival.
The carnival cost $15.50 for the first person and $12.00
for each additional person.
Equation: c = 15.5 + 12f
C = cost
f= number of friends
If the input of the equation is 3, what is the output?

Astudent simplified a rational expression as shown.

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
