Julie is a math tutor. she charges each student $210 for the first 7 hours of tutoring and $20 for each additional hour.
when the number of hours (h) that julie spends tutoring a student is greater than 7 (h > 7), the equation that gives the amount (a) that julie earns in dollars is . if julie earns $410 tutoring one student, the total number of hours she spent tutoring the student is .
amount a.
a=210+20(h+7)
a=210+20(h-7)
a=-210+20(h-7)
a=210+(h-7)/20
total number.

How many solutions does the nonlinear system of equations graphed bellow 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 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.
