How do you do 8y + 5 - 4y +1 =46

Y=10

Step-by-step explanation:

You need to isolate the variable "y"

To do this simply subtract the whole numbers, 5 and 1, from the left side of the equation and add the y values together.

This leaves you with "8y-4y=46-5-1" which simplifies to "4y=40"

Now you simply divide both sides of the equation by the number with the variable y, being 40/4 , leaving you with "y=10"

24+x=y

step-by-step explanation:

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.
