Will mark brainliest! the value of x in the solution to the system 2x-3y = - 2 3x - 2y = 12 is

2x - 3y = - 2

3x - 2y = 12

the value of X in the solution to the system is 4.

-4x+6y=4

9x-6y=36

5x=80

x=8

24-12y=12

-12y=-12

y=1

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.
