Which of the following is the best first step to convert the following equation to slope intercept form?
2-4y =-12

y=7/2 in decimal form 3.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2-4*y-(-12)=0

Pull out like factors :

  14 - 4y  =   -2 • (2y - 7)

  Solve  :    2y-7 = 0  

Add  7  to both sides of the equation :  

                     2y = 7

Divide both sides of the equation by 2:

                    y = 7/2 = 3.500

1/3 + 1/5 = 8/15.

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.
