N² - 49 = 0
<u>   + 49  + 49</u>
        n² = 49
         n = <u>+</u>7

The solution to the problem is {7, -7}.

So n^{2} - 49 = 0
Add 49 from 0 and you get
n ^{2} = 49
Only 7^{2}= 49 so n = 7

Erin writes the set of ordered pairs below. The set represents a function.
tino4ka555 [31]
Point A shows that she is incorrect.
With functions, you can perform the "straight line test through each point. If the line goes through both points, you know it's not a function.
If we plotted point A, it'd fail the straight line test because the given point (-6, 7) already has -6 as an x value.
Hope this helps!

Is 26,341 divisible by 3?
shepuryov [24]

No.  26,341 is not evenly divisible by 3 .

Here's the trick you can use to decide this
just by looking at a big number:

==>               If a number is divisible by 3, then the
                     sum of its digits is divisible by 3.

I've never taken the trouble to figure out why this works,
but it does work.  I didn't make it up.  It's widely known.

So let's look at  26,341 .

The sum of the digits is  (2 + 6 + 3 + 4 + 1)  =  16 .

16  is not divisible by  3 , so  26,341  is not divisible by  3 .

Is that cool or what !
