A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations".

How to simplify this expression ?

Musya8 [376]

Answer:

$\large \boxed{\sf \ \ \dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{2x+1}{x^2(x+1)} \ \ }$

Step-by-step explanation:

Hello,

This is the same method as computing for instance:

$\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{3+2}{2*3}=\dfrac{5}{6}$

We need to find the same denominator.

Let's do it !

For any x real different from 0, we can write:

$\dfrac{1}{x^2}+\dfrac{1}{x^2+x}=\dfrac{1}{x^2}+\dfrac{1}{x(x+1)}\\\\=\dfrac{x+1+x}{x^2(x+1)}=\dfrac{2x+1}{x^2(x+1)}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

G(x)=3x+2(x+1) evaluate g(7)

lianna [129]

G(x) = 3x + 2(x + 1)

g(7) = 3(7) + 2(7 + 1)

g(7) = 21 + 2(8)

g(7) = 21 + 16

g(7) = 37

Hurrrryyyyy plllzzz. Determine the equation of the line that passes through the given points

pashok25 [27]

<h2>Answer:</h2>

y = 2

<h2>Step-by-step explanation:</h2>

To determine the equation of the line that passes through (10,2) and (-3,2), we need to determine the slope of the line. Then substitute the slope and any given point in point slope form to obtain the equation of the line.

<h3>Finding the Slope of the line:</h3>

$\implies \text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }$
