Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions y > 5x5 y> 5x+5 part b: is the point (-2,5) included in the solution area for the system? justify your answer mathematically (4 points)

a=r

d=q

c=p

b=s

hope this !

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.
