What is the scale factor of 3,6 and 4.5, 9

If i have one apple and give you the apple, how many apples do i have?

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

How can you tell when x and y are not directly proportional?
