He students in an 8th Grade class had a dance. They spent $500 for a local band. The equation shown can be used to find the total profit, y, if the students sold x tickets to the dance. y = 4x - 500

What does the 4 represent in the equation?
A. the price per ticket

B. the cost of the band

C. the number of tickets sold

D. the profit made from selling x tickets

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.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
