7\sqrt{50x^{15}y^{21}}=7\sqrt{25\cdot2x^{14+1}y^{20+1}}=7\sqrt{25}\cdot\sqrt{x^{14}}\cdot\sqrt{y^{20}}\cdot\sqrt{2xy}\\\\=7(5)\sqrt{(x^7)^2}\cdot\sqrt{(y^{10})^2}\cdot\sqrt{2xy}=35x^7y^{10}\sqrt{2xy}\\\\Used:\\\\\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\\sqrt{a^2}=a\\\\a^n\cdot a^m=a^{nm}\\\\(a^n)^m=a^{nm}

If f(x) = 7x-6, which of the following is the inverse of f(x)?
Harman [31]

Answer:

f^{-1}(x) = \frac{x+6}{7}

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject, that is

y = 7x - 6 ( add 6 to both sides )

y + 6 = 7x ( divide both sides by 7 )

x = \frac{y+6}{7}

Change y back into terms of x, hence

f^{-1}(x) = \frac{x+6}{7}

Is -1/2n + 1 1/2n+3-n equivalent to 3? Explain plz
liraira [26]
No, you can combine like terms like this (-1/2 + 11/2 -1)n +3 =3. Then you just simplify to see if the two sides of the equation match. You get 4n+3=3 which is not always true so the original equation is not true.

Feel free to ask any questions.
