Answer:

All of them.

Step-by-step explanation:

For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator.

Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:

x(x-1)(x^2-4)=0

Zero Product Property:

x\neq 0\text{ or }x-1\neq 0\text{ or }x^2-4\neq 0

Solve for the x in each of the three equations. The first one is already solved. Thus:

x-1\neq 0 \text{ or }x^2-4\neq 0\\x\neq 1\text{ or }x^2\neq 4\\x\neq 1 \text{ or }x\neq\pm 2

Thus, the values that <em>cannot</em> be in the domain of the rational function is:

x=-2,0,1,2

Click all the options.

Answer:

\Large \boxed{\mathrm{All \ options}}

Step-by-step explanation:

The domain of a function are all possible values for x.

To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are <em>not</em> included in the domain, since the denominator of 0 would make the rational function undefined.

x(x-1)(x^2-4)=0

Setting the factors equal to 0.

x=0 \\ \\ \\\\ x-1=0 \\ \\ x=1 \\ \\ \\ \\ x^2 -4=0 \\ \\ x^2 =4 \\ \\ x=\pm 2

The values of x that are <em>not</em> in the domain of the rational function are x=-2, x=1, x=2, and x=0.

What is the y-intercep is (0,-1) and slope is 4
lana [24]

Answer:

y = 4x - 1

Step-by-step explanation:

Assuming you require the equation of the line.

The equation of a line in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = - 1, thus

y = 4x - 1 ← equation of line

Two systems of equations are shown below: System A System B 3x + 2y = 3 −x − 14y = 1 −2x − 8y = −1 −2x − 8y = −1 Which of the fo
Sauron [17]

The two linear equations represented in system A as :

3 x + 2 y =3   -------(1)

- 2 x - 8 y = -1  ------(2)

(1) × 2 + (2) × 3 gives

⇒ 6 x + 4 y - 6 x - 24 y = 6 -3

⇒ - 20 y = 3

⇒ y = \frac{-3}{20}

Putting the value of y in equation (1), we get

3 x  - \frac{6}{20}=3\\\\ 3 x= \frac{66}{20} \\\\ x=\frac{11}{10}

Two linear equation represented in system B is:

3.   -x - 14 y =1

4.   - 2 x - 8 y = -1

-2 ×Equation (3) + Equation (4)=

2 x +28 y- 2 x - 8 y= -2 -1

⇒ 20 y = -3

⇒y =\frac{-3}{20}

Putting the value of y in equation (3),we get

-x + \frac{42}{20}=1 \\\\ x=\frac{22}{20}=\frac{11}{10}

As Two system , that is system (A) and System (B) has same solution.

By looking at all the options , i found that Option (D) is correct. The two system will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

Which of the following equations could be the result of using the comparison method to solve the system shown?
masya89 [10]

Answer:

6-2y=4y+8

since you show x through y

Answer:

The result that is obtained on comparing the system of equations in order to get the solution to the system of equations is:

   6 -2y =4y + 8

Step-by-step explanation:

We are given a system of equations in term of variable x and y as follows:

                                x + 2y = 6 --------(1)

                           x - 4y = 8-------------(2)

From equation (1) we have the value of x in terms of y as:

                          x=6-2y

From equation (2) we have the value of x in terms of y as:

                         x=8+2y

Hence, on equation the above two values of 'x' we obtain:

                         6 - 2y = 4y + 8
