If this is also for the inequality 4 < 8, then:

4 < 8 / /(-2)

-2 > -4

It is true, because the sign also changed.

Simplify 8 over negative 4 divided by negative 3 over 9. 6 −6 12 −12

skelet666 [1.2K]

Answer:

Step-by-step explanation:

Given

$\frac{8}{-4} / \frac{-3}{9}$

Required

Solve

$\frac{8}{-4} / \frac{-3}{9}$

We start by converting the division sign to multiplication

$\frac{8}{-4} / \frac{-3}{9} =\frac{8}{-4} * \frac{-9}{3}$

Then, we divide -9 by 3

$\frac{8}{-4} / \frac{-3}{9}=\frac{8}{-4} * -3$

Then, we divide 8 by -4

$\frac{8}{-4} / \frac{-3}{9}=-2 * -3$

Multiply -2 and -3 to give final result

$\frac{8}{-4} / \frac{-3}{9} = 6$

Hence, $\frac{8}{-4} / \frac{-3}{9}$ is equivalent to 6

When Kimchi is made, it is initially fermented for the first 3 days at a temperature of 70 degrees Fahrenheit and then immediate

svet-max [94.6K]

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

$\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}$

Please find attached the graph of the step function?

<h3>How can the step function be written?</h3>

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

$\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}$

The graph of the above function created with MS Excel is attached

Give an example of a function g(x) such that has vertical asymptotes at x = −1 and x = 2.

BigorU [14]

Answer:

$\frac{69420}{(x+1)(x-2)}$

Step-by-step explanation:

An asymptote of a vertical line is one that the graph can't exactly reach, but can get as close as you want it to be (as long as the distance is not 0), while the x- or y-coordinates tend to plus/minus infinity. An example of where this happens is when filling in the x-value would result in a zero in the denominator, hence the answer.
