Question

Two rails are represented by the equation x+2y-4 =0 and 2x+4y-12=0 this represents situation graphically ​

Answer 1

Answer:

Hey There!

Let the two equations be

1. x+2y=4
2. 2x+4y=12

Now let's solve for equation 1.

Let x=0

$0 + 2y = 4 \\ 2y = 4 \\ \\ \therefore \: y = \frac{ \cancel{4} \: \: ^{2} }{ \cancel{2}} \\ \\ y = 2 \\ \\ x = 0 \: and \: y = 2 \: is \: \\ the \: solution$

(0,2)

Let y=0

$x + 2(0) = 4 \\ x + 0 = 4 \\ x = 4 \\ \\ x = 4 \: and \: y = 0 \: is \: the \: \\ solution$

(4,0)

Now solve for equation 2.

$2x + 4y = 12$

Let x=0

$2(0) + 4y = 12 \\ 4y = 12 \\ \\ \therefore \: y = \frac{ \cancel{12} \: \: ^{3} }{ \cancel{4}} \\ \\ x = 0 \: and \: y = 3 \: is \: \\ the \: solution$

(0,3)

Let y=0

$2x + 4(0) = 12 \\ 2x = 12 \\ \\ \therefore \: x = \frac{ \cancel {{12}} \: \: ^{6} }{ \cancel{2}} \\ \\ x = 6 \\ \\ x = 6 \: and \: y = 0 \: is \: \\ the \: solution$

(6,0)

Answer 2

Answer:

No. Two atoms of the same chemical element are typically not identical. ... Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
