choose a system of equations with the same solution as the following system:

4x − y = −11
2x + 3y = 5

a. 12x − 3y = −33
10x − 6y = −38

b. −4x − 9y = −21
−2x − 7y = −27

c. 4x + 3y = 5
10x + 5y = −1

d. 2x − 4y = −16
4x − 4y = 44

24+x=y

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.
