On the first day, 8 adult tickets were sold and 13 student tickets were sold for a total of $75. On day two, 10 adult tickets were sold and 9 student tickets were sold for a total of $72. What is the cost of an adult ticket? What is the cost of a student ticket?

An adult ticket cost $4.50 and a student ticket cost $3.00

Step-by-step explanation:

I had to guess and check(not reliable)

8x4.50=36

13x3=39

36+39=75

So...

10x4.50=45

9x3=27

45x27=72

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

positive

step-by-step explanation:

the quadrant is facing upwards
