PLEASE HELP I WILL GIVE BRANLIEST Sarah is self-publishing her 300-page novel and wants to estimate the printing costs.

Answer the questions to estimate the cost of printing a 300-page paperback book.

1. What is the y-intercept for the trend line? What is the real-world meaning of this point?

2. One point on the trend line is (200, 6). Using this point and the y-intercept, find the slope of the trend line. Show your work.

3. What is the real-world meaning. of the slope?

4. Use the slope and y-intercept to write an equation for the trend line in slope-intercept form.

5. Use your equation to estimate the cost of printing Sarah's 300-page book.​

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

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.
