Answer:

A

Step-by-step explanation:

You can eliminate B and D because it’s using \frac{g}{f}, but the question is asking \frac{f}{g}. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠ \sqrt{7} part of it is what makes it true.

The reason being is that the only thing that won’t make \frac{2x+1}{x^{2}-7 } true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug \sqrt{7} for x in the denominator you get: \sqrt{7^{2} } -7. The \sqrt{7^{2} } part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal \sqrt{7}.

<u>So the answer is A:</u>  \frac{2x+1}{x^{2}-7}, x\neq ± \sqrt{7}

There you go my friend!

I hope you understand and that this helps with your question! :)

These are the two rules for when a and b are positive numbers.
a + b = b + a
a - b ≠ b -a
a - b = -b + a

For example:

5.71 + 2.84 = 2.84 + 5.71
8.55 = 8.55

5.71 - 2.84 ≠ 2.84 - 5.71
2.87 ≠ -2.87

5.71 - 2.84 = -2.84 + 5.71
2.87 = 2.87



These are the rules for when a and b are negative numbers.
a + b = b + a
a - b = b + a

For example,

-6.2 + (-3.96) = -3.96 + (-6.2)
-6.2 - 3.96 = -3.96 - 6.2
-10.16 = -10.16

-6.2 - (3.96) = -3.96 + (-6.2)
-10.16 = -10.16



Also, if a is a positive number, while b is a negative number, we see these rules:
a + b = a - b
a - b = a + b

For example,

5.71 + (-6.2) = 5.71 - 6.2
-0.49 = -0.49

5.71 - (-6.2) = 5.71 + 6.2
11.91 = 11.91


Also, if a is a negative number while b is a positive number, then these rules will apply:
a + b = b - a
a - b = -b - a

For example,

-3.96 + 2.84 = 2.84 - 3.96
-1.12 = <span>-1.12
</span>
-3.96 - 2.84 = -2.84 - 3.96
-6.8 = -6.8


I hope this helps! :)
