Answer:

x = 3

Step-by-step explanation:

In order to solve this equation, first we need to make the equation easier to read.

So instead of:

8x - (-5) = 29

We will do:

8x + 5 = 29

<em>(</em><em>Note</em><em> </em><em>that</em><em> </em><em>we</em><em> </em><em>have</em><em> </em><em>a</em><em> </em><em>plus</em><em> </em><em>sign</em><em> </em><em>now</em><em>,</em><em> </em><em>because</em><em> </em><em>subtracting</em><em> </em><em>a</em><em> </em><em>negative</em><em> </em><em>number</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>as</em><em> </em><em>adding</em><em> </em><em>a</em><em> </em><em>positive</em><em> </em><em>number</em><em>.</em><em>)</em>

Next we move the 5 to the other side of the equal sign, by subtracting it.

Now we have:

8x = 24

Finally we isolate the x variable, by dividing by 8 on both sides.

(24 ÷ 8 = 3)

Our answer is 3, therefore x = 3.

Hope this helps you :)

Which of the following rational functions is graphed below?
Zepler [3.9K]

Answer:

  D.  F(x) = 1/(x +5)²

Step-by-step explanation:

The vertical asymptote at x=-5 tells you that x=-5 will be a zero of the denominator. The only equation with a denominator factor of (x+5) is ...

  F(x) = 1/(x +5)²

_____

<em>Additional comment</em>

The fact that the value of F(x) does not change sign at the vertical asymptote tells you the denominator factor will be of even degree. That is taken for granted here, as all denominators are squares in the answer choices.
