Answer:
Step-by-step explanation:
Using the Foil method
you multiply x times x and get
Then you multiply -4 times X and get -4x
Then you multiply -3 times X and get -3x
then you add -4 and -3 together and get -7x
Lastly you multiply -4 and -3 and get 12
And there you have it
See the explanation
<h2>Explanation:</h2>
A system that has one or infinitely many solutions is called <em>consistent. </em>If an equation in a system tells us no new information then the equations of the system are <em>dependent. </em>In other words, to find an equation that creates a consistent and dependent system with the given equation we have to get the same line:
The given line is:
If we multiply both sides of the equation by a constant we will have the same line when plotting, therefore let's multiply by 3:
So a system of two linear equation that is consistent and dependent is:
