Sketch the graph of the function.

x= y^2 + 3x^2

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

Hi, can anyone show me how to do this problem? 100 points for this. in advance

Angles r and s are complementary. the measure of angle r is 31 degrees. which equation can be used to find angle s?
