Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,620 was collected on the sale of 1,104 tickets. How many of each type of ticket were sold?

adult=379, student=725

Step-by-step explanation:

Given

Total tickets sold for $2620

total  no of tickets 1104

The cost of an adult ticket is $5

The cost of a student ticket is $1

Suppose there are x adults and y students

So, we can write

Put the value of y from (i) into (ii)

Similarly,

what is the graph

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.
