Sports The tables list the average ages of players on 15 teams randomly selected from the 2010 teams in the National Football League (NFL) and Major League
Baseball (MLB). Describe how the average ages of NFL players compare to those of
MLB players.

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.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
