Is δ pmr similar to δ smn ? if so, which postulate or theorem proves these two triangles are similar?

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

What is the equation of the line that is parallel to the line with the equation y= -3/4x +1 and passes through the point (12,-12)
