ANSWER THESE IN 20 MINS FOR A BRAINLIEST Sketch the graph of each linear inequality: 1) x<-5

3) 3x-2y<10

4) 5x-3y<-15

5) 1 y >4

6) x-y>2

ok wait, how do you want us to answer them

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.
