Janelle and swetha are taking a 50 question test. janelle started after swetha had already finished 12 questions. janelle answers questions at a rate of two per minute while swetha answers at a rate of 5 questions per 4 mins. janelle eventually catches up to swetha. how many minutes does it take her and what question are they on when janelle catches up? make 2 equations in slope intercept form (y=mx+b) for janelle and swetha to solve.

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
