Given : The Relationship between the Average Rating for the Hotel and the Average Daily Price of the Room of the Hotel is expressed by the Equation :

✿ Y = 65X + 55

Where : X is the Average Rating of the Hotel from 0 to 5 Stars and Y is the Average Price of the Room

For a 3-Star Hotel Room, X is Equal to 3

⇒ The Average Room Price for a 3-Star Hotel Room = [65(3) + 55]

⇒ The Average Room Price for a 3-Star Hotel Room = [195 + 55]

⇒ The Average Room Price for a 3-Star Hotel Room = $250

Find the length of a segment with endpoints Y(2, 8) and Z(- 2, 5) .

Andrej [43]

<em>The distance the length of a segment with endpoints Y(2, 8) and Z(-2, 5) is 5 units</em>

<h2>Explanation:</h2>

Endpoints of a Line segments are places where they end or stop. Line segments are named after their endpoints. In this case, those endpoints are Y and Z, so the line segment would be:

$\overline{YZ} \ or \ \overline{ZY}$

To find the length of this segment with endpoints Y(2, 8) and Z(-2, 5), let's use the Distance Formula:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

$Let's \ write: \\ \\ Y(x_{1},y_{1}) \rightarrow Y(2, 8) \\ \\ Z(x_{2},y_{2}) \rightarrow (-2, 5) \\ \\ \\ Substituting: \\ \\ d=\sqrt{(-2-2))^2+(5-8)}^2 \\ \\ d=\sqrt{(-4)^2+(-3)^2} \\ \\ d=\sqrt{16+9} \\ \\ d=\sqrt{25} \\ \\ \boxed{d=5}$
