Two tickets to an ice skating performance costs $36. For five tickets it costs $90, and for nine tickets it
costs $162.
Model with Math Use the graph to determine
whether the number of tickets and the cost have a
proportional relationship. If so, what is the constant
of proportionality and what does it mean?

70,000 + 6,000 + 800 + 30

step-by-step explanation:

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.

answer: y=0 if that is what u r looking for

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
