Answer: VI)

$\frac{x - 1}{3(x+ 1)}$

VII)

$\frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

Step-by-step explanation:

VI)

$\frac{{(x + 1)}^{2}}{6} \times \frac{2}{{x}^{2} - 1}$

$= \frac{2{(x - 1)}^{2} }{6(x - 1) \times (x + 1)}$

$= \frac{x - 1}{3(x+ 1)}$

VII)

$\frac{{m}^{2} - 49}{3n} \div \frac{2n - 14}{6}$

$= \frac{(m - 7) \times (m + 7)}{3n} \times \frac{6}{2(n - 7)}$

$= \frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

You have to add them all together and times that by 60%, when you get 13.8 that's the answer and to prove it, subtract 23-13.8 and you get 9.2 and that's 40%

What is the inverse function for f(x)= square root of 1/2x+4

Zepler [3.9K]

The inverse of f(x) would be f(x) = 2 $x^{2}$ - 8.

We can find this by taking the original equation and switching the x and f(x). Once we do this, we solve for the f(x) in its new place and that is the inverse equation. It is taken step by step for you below.

Take the original.

f(x) = $\sqrt{\frac{1}{2}x + 4}$
