Answer:

Hey! so the answer is 20%

Step-by-step explanation:

If you want to know what percent 16 is of 80, you simple divide 16 by 80, then take that number and move the decimal place two spaces to the right. That's your percentage!

If $f^{-1}(x)$ is the inverse of $f(x)$ , then by definition of inverse functions,

$\left(f\circ f^{-1}\right)(x) = f\left(f^{-1}(x)\right) = x$

Given $f(x) = 2x-8$ , the inverse, if its exists, satisfies the equation above. Evaluate $f$ at the inverse, we have

$f\left(f^{-1}(x)\right) = 2 f^{-1}(x) - 8 = x$

Solve for the inverse:

$2 f^{-1}(x) - 8 = x$

$2 f^{-1}(x) = x + 8$

$\boxed{f^{-1}(x) = \dfrac12 x + 4}$

Given $g(x) = \frac13 x + 5$ , we do the same thing as before to find its inverse.

$g\left(g^{-1}(x)\right) = \dfrac13 g^{-1}(x) + 5 = x \implies \boxed{g^{-1}(x) = 3x - 15}$

Answer:

r equals start fraction cap a minus p over p t end fraction

Step-by-step explanation:

Subtract the term non containing r, then divide by the coefficient of r.

$A=p+prt\\\\A-p=prt\\\\\dfrac{A-p}{pt}=r$

Answer

|-12|+|45|=|12|+|45|= 12+45=57

Step-by-step explanation:

When you take the absolute value of a negative number it is the same thing as taking as a positive number. The absolute value is just that number. Once you teach the absolute value of each number perform the operation given In the problem.
