Easy question just too lazy to do it a total of 700 tickets were sold for the school play. they were either adult tickets or student tickets. there were 50 fewer student tickets sold than adult tickets. how many adults tickets were sold?

300 student tickets and 400 adult tickets

Step-by-step explanation

if theres a total of 700 tickets so divide that buy two you get 350 for adults and 350 for student, but then it says 50 fewer student tickets were sold meaning there was 50 more adult tickets so 400 adults and 300 for students. hope that was correct!

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
