Which graph represents the solution to the given system -4x+3y+-12 and -2x+3y+-18? I was not able to put the graphs on here so I put the solutions on here that were on each of the graphs. A. (2.67, -2)
B. (-3, -8)
C. (1, -5.33)
D. (-1, -5.33)

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.

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:
