PLEASE HELP! I'M TIMED Willis analyzed the following table to determine if the function it represents is linear or non-linear. First he found the differences in the y-values as 7 – 1 = 6, 17 – 7 = 10, and 31 – 17 = 14. Then he concluded that since the differences of 6, 10, and 14 are increasing by 4 each time, the function has a constant rate of change and is linear. What was Willis’s mistake? x: 1 2 3 4 y: 1 7 17 31 He found the differences in the y-values as 7 – 1 = 6, 17 – 7 = 10, and 31 – 17 = 14. He determined that the differences of 6, 10, and 14 are increasing by 4 each time. He concluded that the function has a constant rate of change. He reasoned that a function that has a constant rate of change is linear.

The sum of two numbers is 86, and their difference is 20. find the two numbers

Solve the system of equations y= 3/2 - 1, -x+ y =-3

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 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
