Answer:

given \: x =  -  \frac{1}{7}

x {}^{2}  +  \frac{1}{x {}^{2} }

(  - \frac{1}{7} ) {}^{2}  +  \frac{1}{  (  - \frac{1}{7} ) {}^{2} }

\frac{1}{49}  +  \frac{1}{ \frac{1}{49} }

\frac{1}{49}  +  \frac{1 \times 49}{1}

\frac{1}{49}  + 49

\frac{2402}{49}  \: or \: 49.02

Answer:

Step-by-step explanation:

Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.

x + 2x + 5 + 6x - 17 + 3x + 2 becomes

12x - 10

Trava [24]

Answer:

domain - (-infinity,infinity)

range - (-infinity, 2]

axis of sym - x=-1

y int - (0,-1)

at what value (row 1) - (-1,2)

Step-by-step explanation:

domain is side to side, it never ends bc of the arrows

range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)

the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up
