Clarissa wants to go see luke bryan in concert. tickets cost $54.50 each. clarissa already has $25 saved and is going to save $5 per week from her allowance. im how many weeks will she be able to afford the ticket?

6 Weeks

Step-by-step explanation:

Let x be the number of weeks before Clarissa had enough money to buy a ticket to the Luke Bryan Concert

25 + 5x > 54.50

5x > 29.5

x > 5.9

x = 6

She will be able to afford the ticket in 6 weeks

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.
