I NEED THIS ANSWER IN LIKE 3 MINUTES. HELP!! 3x+2y=24, -x+2y=16
solve the system of linear equations by elimination.

(9/2, 21/4)

Step-by-step explanation:

3x+2y=24

- -x+2y=16

4x=18

4x/4

18/4

x=9/2

3(9/2)+2y=24

27/2 +2y=24

-27/2      -27/2

2y= 21/2

y=21/4

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.
