The time needed to roast a chicken depends on its weight. Allow at least 15 min/lb for a chicken weighing up to 6 lbs. Allow at least 20 min/lb for a chicken weighing more than 6 lbs. Let y represent the time in minutes needed to roast a chicken of weight x, where x is measured in pounds. Which inequalities represent the time needed to roast a chicken?
a. y > 15x for x < 6 and y > 20x for x > 6 c. y > 15x for x < 6 and y > 20x for x > 6
b. y > 15x for x < 6 and y > 20x for x > 6
d. y > 15x for x < 6 and y > 20x for x > 6

no one knows lol

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.
