Agroup of people bought movie tickets at the amc century city. they bought a total of 7 tickets, some adults and some kid tickets. they spent a total $72. if adult tickets cost $12 and kid tickets cost $9, how much of each were purchased? could some one give me the 2 equations for this problem

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

Identify the graph of y = ln x + 1.

Find the solution of this system of equation -7x+y=-20 9x-3y=36
