If f(x)=3x+2, what is f(5)
patriot [66]

Answer:

<h2>f(5) = 17</h2>

Step-by-step explanation:

f(x)=3x+2

To find f (5) replace every x in f(x) by 5

That's

f(5) = 3(5) + 2

= 15 + 2

<h3>= 17</h3>

Hope this helps you

Please, I need help ASAP!
enot [183]

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! :)
