<h2>Answer:</h2>
The domain of the given function is:
i.e. [5,∞)
Domain of a function--
The domain of a function is the set of all the possible values of x for which the function is defined.
That is it is the collection of all the points except the excluded values of the function.
The function f(x) is a square root function which is given by:
We know that the domain of the function depends on the domain of the square root quantity.
We know that: a square root function is well defined when the quantity under the square root is non-negative

The image lines constructed are called parallel lines. They are parallel because they are all equidistant to each other at every point and at no point between any of the lines will there be an intersection of the three lines.
<h3>What does it mean for two or more lines to be equidistant from each other?</h3>Equidistance is simply another word for equal in distance. That is, parallel lines maintain equal distance from each other at all points along them.
See the attached construction as well as more insights about parallel lines from the link below.

Answer:
B) -3
Step-by-step explanation:
1. First you have to write the equation in slope intercept form. To do that, you must have y be alone on one side.
2. move the 3x to the right side with the 5 by subtracting 3x from both sides. Since 3x will cancel on the left, y will be left alone.
3. Now that you're in slope intercept form, you can find the slope easily. The slope will always be the number in front of x. In this case, the number in front of x is -3. Therefore, -3 is your slope!
