Is there a hole in y=4x/x^3-4x

Hello Ramirez,

I assume that you meant to put parenthesis around the entire expression for the denominator: (x^3 - 4x). 

If so, then you would have a hole wherever the denominator is zero, because it would be undefined.

So let's factor: x^3 - 4x
First factor out an x to get x(x^2 - 4).
Then, we have the difference of squares, so we can factor it to: x(x+2)(x-2)

If we set that equal to zero, there are 3 possible solutions.

0, 2, and -2

These inputs would make the denominator zero and you would have a hole on your graph.

I hope this helps,
MrEQ

So you have 12 cases delivered in 1 hour and 30 minutes. 30 minutes is half of an hour or .5

so 12/1.5 is 8, that is 8 cases per hour for a total of 32 cases in 4 hours.

8-5(x+2)&lt;-5 what is the inequality with a line graph
Vadim26 [7]

The expression for the inequality is:

8-5(x+2)

We need to find which line represents this inequality. To do that we will use the left side of the inequality and rewrite it as a slope-intercept form. Which is done below:

\begin{gathered} y(x)=8-5(x+2) \\ y(x)=8-5x-10 \\ y(x)=-5x-2 \end{gathered}

The line for this inequality is "-5x -2". Where the slope is -5 and the y-intercept is -2. We can graph it as shown below:
