You went 3 family members planet drive to a state fair on saturday traffic on the way down was frustrating when you get there you find the cost $4 per person to get in and each ticket is $0.25 each ride is one ticket write an equation in slope intercept form where y represents total cost and x represents the number of tickets how much would the total cost be if each member of your family road 4 rides

y = 0.25x + 4     20 dollars

Step-by-step explanation:

you and 3 family members (4 people)

4 dollars per person, so 4 times 4 = 16

.25 a ride and everybody rode 4 rides.

.25 * 4  = 1.00

1.00 * 4 = 4.00

16 + 4 + 20

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.
