Iforget how to use fractions, what's 7 times 1/2

100 points, hi, i’m not sure how to get the equation from the graph and table.

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

Which of the choices shown could be used to prove that aacp=abcp ?
