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! :)

Vhat is the equation of the line that is parallel to the
ozzi

Step-by-step explanation:

second one because

only x+2y=8 passes through the point (2,3)

the proof is 2+2*3=2+6=8

if we replace the given point to the other equations we will take wrong results for example

first equation

x+2y=4. 2+2*3=2+6=8 that is not equal to 4
