Timed test please help. Can someone please help me explain how you graph the circle from the equation below and how you find the center and the radius? I will mark brainliest.

Solve 3x-18=2y and 5x-6y=6 by elimination show work

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e

Given the equation −4  = 12, solve for x and identify if it is an extraneous solution.
