The price of a movie ticket was $4.41 less this week than last week. This week, the price to buy 5 tickets is $68.27.
Write an equation and solve for the price of a single ticket
last week. Your answer as a decimal should not extend
beyond the hundredths place for money ($0.01) and may
need to be rounded to the nearest cent. $ is not needed as
a unit.

13.65.  

Step-by-step explanation:

68.27 divided 5

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
