Find the distance between the points E(3, 7) and F(6,5).

zmey [24]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ E(\stackrel{x_1}{3}~,~\stackrel{y_1}{7})\qquad F(\stackrel{x_2}{6}~,~\stackrel{y_2}{5})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ EF=\sqrt{(6-3)^2+(5-7)^2}\implies EF=\sqrt{3^2+(-2)^2} \\\\\\ EF=\sqrt{9+4}\implies EF=\sqrt{13}\implies EF\approx 3.61$

What is the function of xy=17

Murljashka [212]

Answer:

x = 17 + y

Step-by-step explanation:

Simplifying

x + -1y = 17

Solving

x + -1y = 17

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'y' to each side of the equation.

x + -1y + y = 17 + y

Combine like terms: -1y + y = 0

x + 0 = 17 + y

x = 17 + y

Simplifying

x = 17 + y
