a. Is there a proportional relationship between the weight and the cost
of clay? Explain your answer.
b. What does the point (5, 12.5) mean in this situation?

Can someone explain the elimination method to me for this problem?

Write the sentence as an equation. b increased by 281 is d

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
