Mark drew the following model and said it represent the promblem 21÷4. is marks model correct? if so what is the quotient and remainder?

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

Solve 3x-18=2y and 5x-6y=14 by elimination or substitution . show all !

(-y to the power of 2 - 4y- to the power of 2 -6 y +3)
