The x-intercept is point where the graph cuts the x-axis, while the y-intercept is the point where the graph cuts the y-axis. The y-intercept in a straight line equation normally represents some initial amount. Thus the correct answer that can be deduced from our graph is:
x-intercept is 400
y-intercept is 800

Thus the correct description is:

Please help asap<br><br> solve x^4+5x^2+4=0

const2013 [10]

Answer:

$x=\pm i\text{ or }x=\pm2i$

Step-by-step explanation:

So we have the equation:

$x^4+5x^2+4=0$

Let's let u be equal to x². So:

$u^2+5u+4=0$

Factor:

$(u+1)(u+4)=0$

Zero Product Property:

$u+1=0\text{ or } u+4=0$

Subtract:

$u=-1\text{ or }u=-4$

Replace:

$x^2=-1\text{ or }x^2=-4$

Take square root:

$x=\pm\sqrt{-1}\text{ or }x=\pm\sqrt{-4$

Simplify:

$x=\pm i\text{ or }x=\pm2i$

-3 1/2x - 4 = -38 1/8<br><br> How do I do this?

abruzzese [7]

Hello, I will try my best to explain this to you as simple as possible.

First, you have to pass the -4 to the other side, like this:

-3 1/2x - 4 = -38 1/8

↓

-3 1/2x = -38 1/8 - 4

Then, you have to subtract -4 from -38 1/8, like so:

-3 1/2x = -38 1/8 - 4

↓

-3 1/2x = -42 1/8

My preferred method for this next step is this:

-3 1/2x = -42 1/8

↓

-7/2x = 337/8

Then, we divide:

-7/2x = -42 1/8

↓

x = (-337/8) / (-7/2)

x = 12.0357142857

So, the answer is: 12.0357142857.

Hope this helped! c:
