What is the distance between the points (2, 5) and (5,7)?

Svetlanka [38]

Answer:

$\sqrt{13}$

Step-by-step explanation:

The distance formula that gives the distance between two points is given as:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Plugging in our given points, we get:

$d=\sqrt{(5-2)^2+(7-5)^2},\\d=\sqrt{3^2+2^2},\\d=\sqrt{9+4},\\d=\fbox{$\sqrt{13}$}$ .

What is parallel to 3x-4=1

Licemer1 [7]

Answer:

<h2>x = a, where a is any real number</h2>

Step-by-step explanation:

$3x-4=1\qquad\text{add 4 to both sides}\\\\3x-4+4=1+4\\\\3x=5\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{5}{3}\\\\x=\dfrac{5}{3}\to\text{it's a vertical line}\\\\\text{All vertical lines are parallel to the given line.}\\\\x=a\ \text{where}\ a-any\ real\ number$
