Step-by-step explanation: 2x^5 + 4x^4 – x^3 - x^2 + 7= 11

2x^2 - 1= 1

2x^5 + 4x^4 – x^3 - x^2 + 7 is divided by 2x^2 - 1.=11

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! :)

Y=3/5x-1 solve for x
Ne4ueva [31]

Answer:

y= 3/5x - 1

+1             +1

y+1 = 3/5x

((y+1)5) = 3x

divide by 3  both sides

x= (y+1)5 / (3)


hope that helps

Please help as soon as possible 50 points

Answer:

the answer is d. 4x²+x-6

Step-by-step explanation:

In order to combine the fractions, they need to have the same denominator.

So, multiply each of their numerators by the denominator they need to be equivalent.

This would look like this:

3x/x+3 --> 3x(x)/x(x+3)        ---simplify this as--> 3x²/x(x+3)

x-2/x  --> (x-2)(x+3)/x(x+3)  ---simplify this as --> x²+x - 6/x(x+3)

3x                    3x(x)                                     x-2                   (x-2)(x+3)

-----      --->        -----                 and             --------   --->           ---------

x+3                   x(x+3)                                    x                        x(x+3)

now that both fractions have the same denominator, we can add their numerators.

3x² + x²+x-6 = 4x²+x -6

This should now look like this:

4x²+x -6

-------------

x(x+3)
