Drag each number to show whether or not it is a solution to the inequality shown.

inequality: 20≥5+3x

the numbers that work are: -15, 5, 3.5, and 4 3/4

Step-by-step explanation:

20 >= 5 + 3x.  Subtract 5 from both sides and we get 15 >= 3x.  Divide both sides by 3 and we get 5 >=x.  This means that x has to be less than or equal to 5, which means that the numbers that work are: -15, 5, 3.5, and 4 3/4.

y=mx+b is the final answer!   : )

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.
