Using elimination to solve the system 2x + y = 8 and x + y = 4, which of the following could be the first step?
wolverine [178]
Answer: the option A.

The elimination method consist is adding the two equations in a way that one variable be eliminated..

In order to do that you might have to manipulate on of the equations prior to add the two equations.

In this case, ff you multiply the second equation by - 1 you will get

  - x - y = - 4

which you can add to the first equation

   2x + y = 8 to eliminate the y.

What are the coordinates of (-4,-2) rotating 90° counterclockwise?
RUDIKE [14]

Answer:

(2, -4)

Step-by-step explanation:

The rotation of an object <u>turns</u> the object around a <u>fixed point</u> called the center of rotation.  

A <u>rotation</u> of 90° counterclockwise means:

A 90° rotation counterclockwise with the origin (0, 0) as the center of rotation.

The rule for a counterclockwise rotation of 90° about the origin is:

(x, y) → (-y, x)

Therefore:

(-4, -2) → (2, -4)

The graph of the function is shown below. The domain of the function is?
KATRIN_1 [288]

Answer:

The answer to your question is below

Step-by-step explanation:

Domain of a function is the complete set of possible values of "x".

In a radical function, domain must be ≥ 0.

Exercise

                      f(x) =  \sqrt{x + 4}

Then

                        x + 4 ≥ 0

                       x ≥ -4

                      Domain is x ≥ -4 or [-4 , ∞)
