Combined megan and kelly worked 60 hours.kelly worked twice as many hours as megan.how many hours did they each worked?

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Can you me find the slope! (30 points)
