Is the system of equations is consistent, consistent and coincident, or inconsistent? y=4x−4y=−4x+4 Select the correct answer from the drop-down menu.

Respuesta :

Answer: It is consistent as the lines are intersecting lines and it has a unique solution

Step-by-step explanation:

Since we have given two systems of equation :

[tex]y=4x-4\\\\and\\\\y=4x+4[/tex]

We need to check whether the system of equations is consistent or inconsistent.

As we know the formula for checking the consistency :

[tex]\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}[/tex]

In first equation we have

[tex]y=4x-4\\\\4x-y=4\\\\Here,a_1=4,b_1=-1,c_1=4[/tex]

similarly,

In the second equation we have

[tex]y=-4x+4\\\\4x+y=4\\\\Here,a_2=4,b_2=1,c_2=4[/tex]

So, According to question, we have

[tex]\frac{1}{4}\neq \frac{1}{-1}\neq \frac{4}{4}\\\\0.25\neq -1\neq 1[/tex]

Hence, it is consistent as the lines are intersecting lines and it has a unique solution.

Answer:

The given system of equations is consistent.

Step-by-step explanation:

The given equations are

[tex]y=4x-4[/tex]         (1)

[tex]y=-4x+4[/tex]           (2)

Add both equations,

[tex]2y=0[/tex]

[tex]y=0[/tex]

Put this value in 1.

[tex]0=4x-4[/tex]

[tex]x=1[/tex]

Using the elimination method the solution of given equations is (1,0).

Since the system of equations has a solution, therefore the given system of equations is consistent.
