What equation could be used to determine 23% of 122?

ArbitrLikvidat [17]

First, convert 23% into a fraction.

23% =

$23 \div 100 = \frac{23}{100}$

Now the expression to determine 23% of 122 is

$\frac{23}{100} \times 122 \\ = ( \frac{23}{100} )(122)$

Answer:

1 / (x² + 6x + 8)

Step-by-step explanation:

(x + 4) / (x² + 5x + 6) * (x + 3) / (x² - 16)

= (x + 4) / (x + 2)(x + 3) * (x + 3) / (x + 4)(x - 4)

↑ factor x² + 5x + 6 ↑ factor x² - 16 using difference of squares

= 1 / (x + 2) * 1 / (x - 4) ← x + 4 and x + 3 cancel

= 1 / (x + 2) * (x + 4) ← multiply

= 1 / (x² + 6x + 8) ← expand

What is the inverse of the function f(x) = x + 2?

nadya68 [22]

Answer: $h(x)=x-2$

Step-by-step explanation:

To find the inverse of the function $f(x) = x + 2$ , the first step is to replace f(x) with "y":

$f(x) =y= x + 2\\\\ y = x + 2$

The second step is to solve for the variable "x":

$x=y-2$

The third step is to interchange the variables, then:

$y=x-2$

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:

$h(x)=x-2$
