A basketball team sells tickets that cost $10, $20, or, for VIP seats, $30. The team has sold 3362 tickets overall. It has sold 248 more $20 tickets than $10 tickets. The total sales are $65 comma 800. How many tickets of each kind have been sold?

i pretty sure it is

the answer will be b x² +x-1

step-by-step explanation:

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.
