Its 14 (20 chars limit thing)
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.
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)

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) = 
Then
x + 4 ≥ 0
x ≥ -4
Domain is x ≥ -4 or [-4 , ∞)
