If m 3= 54º, find each measure.

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

Is this a polynomial function? i need to know asap

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
