so uh i have a question about STEAM the app ik this is a math website but uh my question is lets say your playing roblox or mine

yawa3891 [41]

Answer:

Step-by-step explanation:

First off, steam isn't a math website.

On discord, it doesn't show steam specifically, but if you're playing a game THROUGH steam then yes, it will show.

To hide this, go to options -> game activity -> and disable "Display currently running game as a status message" on discord.

If you want to hide your status on steam, just put your status to invisible :)

Which equation represents the line shown

murzikaleks [220]

Answer: Third option:

Step-by-step explanation:

The equation in Slope Intercept form of a line that does not pass through the point (0,0), which is known as "Origin, is the following:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

The equation in Slope Intercept form of a line that passes through the Origin, is:

$y=mx$

Where "m" is the slope of the line.

In this case you can observe in the picture attached that the line passes through the point (0,0).

You can also notice that "y" would be the Dependent variable and "x" the Independent variable.

Therefore, the equation of this must have this form:

$y=mx$

The only equation that matches with that form, is the one given in the Third option. This is:

$y=2x$

Preston and Joel are both solving the equation 2x=14. Preston is not sure what to do because he does not know a power of 2 that

Murrr4er [49]

Answer:

yes

Step-by-step explanation:

You can always separate an equation into two parts and see where those graphs intersect.

Joel's method works well.

_____

<em>Additional comments</em>

Preston should know that the invention of logarithms makes it easy to solve equations like this. x = log₂(14) = log(14)/log(2) ≈ 3.8073549.

As for Joel's method, I prefer to subtract the right side to get the equation ...

2^x -14 = 0

Then graphing y = 2^x -14, I look for the x-intercept. Most graphing calculators make it easy to find x- and y-intercepts. Not all make it easy to find points of intersection between different curves.
