Sarah works at an art school and its purchasing canvases for $6 each and bottles of paint for $4 each. she budgets a total of $1,700 for canvases and paint. she goes over-budget, but purchases more than 360 items. which of the following systems of inequalities represents all the possible values for the number of canvases, a, and the number of paint bottles, b, that she buys?

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.

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
