From the description, we have the function f(x)= \sqrt{ \frac{1}{2x-10}+3 }
Since the square root cannot be a negative number, the only thing need to do to find the domain of the function f(x) is take the expression inside the square rot and set it greater or equal than zero:
\frac{1}{2x-10}+3  \geq  0
\frac{6x-29}{2x-10}  \geq 0
\frac{6x-29}{2(x-5)}  \geq 0
x \leq  \frac{29}{6} or x\ \textgreater \ 5

We can conclude that we can use the inequality \frac{1}{2x-10}+3 \geq 0 to find the domain of f(x). Also, the domain of f(x) is (∞,\frac{29}{6}]U(5,∞).

50% because you first subtract the original price from the new price so 126-84 equals 42 then you divide that by the original price 84 which will give you .5 which turns to 50%

Write an equation for each translation of Y=|x|.
Digiron [165]

\boxed{y=\mid x \mid +14}

<h2>Explanation:</h2>

Let's graph the equation:

y=\mid x \mid

Which is the red graph shown below. As you can see this is the pattern of the Absolute Value Function. In order to translate this graph 14 units up, let's add 14 to \mid x \mid. In doing so we get the new function:

y=\mid x \mid + 14

So we get a new graph which is the blue one. In order to prove that this is the correct translation, let's take the vertex of the red graph which is the origin. To translate this graph 14 units up implies that each point is shifted 14 units up, so for the vertex of the red graph:

Vertex \ of \ the \ red \ graph: \\ \\ V(0,0) \\ \\ \\ Vertex \ of \ the \ new \ graph: \\ \\ (0,0+14) \\ \\ (0,14)

So the new vertex matches the vertex of the blue graph. Finally, the equation for the translation of y=\mid x \mid 14 units up is y=\mid x \mid +14
