This is a function because all the x values are different automatically making it a function. But if there were two of the same x values and they had different y values it wouldn’t be a function. Hope that makes sense!

<h3>What is an angle?</h3>

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

Angle ABC has point E on ray BA and point D on ray BC.

Points E and D are equidistant from point B.

The ED distance because if the distance between E and D is even slightly different, the entire angle ABC will vary.

Thus, the identified for the construction is the endpoint of rays BA and BC option (C) is correct.

-8-x=x - 4x<br> Plis help me!!
Makovka662 [10]

Answer:

x = 4

Step-by-step explanation:

Given

- 8 - x = x - 4x, that is

- 8 - x = - 3x ( add 3x to both sides )

- 8 + 2x = 0 ( add 8 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

What is the domain of the function y=2√x-6?<br> 88AX&lt;∞<br> O 0≤x&lt;∞<br> 3≤x&lt;∞<br> 6≤x&lt;∞
Travka [436]

Answer:

If the x-6 is all under the sqrt, the last answer is right:

6<= x <= infinity

If only x is under the sqrt and - 6 is NOT under the sqrt, then:

0 <= x <= infinity is the correct answer.

Step-by-step explanation:

You can look at the equation and or graph to determine the domain of a function. The domain is all the x's that may go into the equation or all the x's on the graph of the function. Inside of a squareroot symbol the number inside there must be positive. While considering the equation, only x's that keep that inside positive can be used.

For sqrt(x-6), x has to be 6 or bigger.

For sqrt(x) - 6, x has to be 0 or bigger.
