Step-by-step explanation:

Mar 10, 2019 · x = (2/5)y + 2 5x + 3z = -5 5[(2/5)y + 2] + 3z = -5 2y + 10 + 3z = -5 2y + 3z = -15 Since this is the same as the second equation if you multiply both halves by -1, we essentially have two unknowns with one equation which has infinite solutions. Therefore the set of …

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.
