If y - b / x - 2 = m then x is equal to

Step-by-step explanation:

The given equation is expressed as

(y - b) / (x - 2) = m

We want to express x in terms of m, b and y. The first step is to multiply the left hand side and the right hand side of the equation by (x - 2). It becomes

(y - b) / (x - 2) × (x - 2) = m(x - 2)

(y - b) = m(x - 2)

The next step would be to divide the left hand side and the right hand side of the equation by m. It becomes

(y - b)/m = m(x - 2)/m

(y - b)/m = (x - 2)

The last step would be to add 2 to the left hand side and the right hand side of the equation. It becomes

[(y - b)/m] + 2 = x - 2 + 2

x = [(y - b)/m] + 2

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

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.
