Using the substitution property of equality, if y= -5 and 7y + x = 11, then ___

1. are the triangles similar and if so why? what is the value of x? show your work.

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36
