Oh! Okay I see. So, the integers MUST be negative for this to work out, or else they will not make any sense. So, we should find the range of both equations and use the overlap.

SO...

The range of |x| + 1 > 7 is (-inf, -6) U (6, inf)

The range of |x+1| <= 7 is [-8, 6]. 

Therefore, the only values that work are -8 and -7. So, the answer would be -15.

The answer should be 0: here is why.

Here is a question for you to think about: Is the absolute value just for positive integers, or for both sides of 0?

In other words, if one number works, then it's negation will to, since the absolute value will be the same.

Therefore, if you add all those 0s up, you will get 0.

(If I'm wrong about this, please let me know!)

Dividing by 0 is undefined. You can imagine it this way:

You have 0 friends and you have 10 cookies. Now, how many cookies does each friend get? You may think the answer is 0, but it acctually is not! This is because you have NO friends, so therefore there is no way to get an answer. 

Now, if you say that you have 10 friends and 0 cookies, each friend will get 0 cookies. This time, we are not dividing by 0, but 0 is divided by us. See the difference?

To complete the square, we see that the second number in the square must be -1. So, "taking" a 1 from the 4, we get:

(x-1)^2+y-5=0

Now, we can see that if we take the y to the other side, we get the equation in vertex form. So, this will become:

(x-1)^2-5=-y

Divide both sides by -1:

-(x-1)^2+5=y

Since this is in vertex form, we see that the vertex is at (1, 5)

We can graph this on desmos: https://www.desmos.com/calculator

And we see that our answer is correct.

So, the vertex is at (1, 5)

Got it, thanks!

Well, it's basically the same reason as: 'Why do people bully". Nobody really knows why this happens, you'll have to ask the prankers yourself. But, right now, people will do anything to get their likes up, whether on Instagram or here. 

Maybe they are being bad just to be bad, or maybe they don't realize that they are being bad, or maybe they are just doing that to get their scores up.

But remember, nobody is perfect, and sometimes, people make mistakes. So, if someone makes a mistake in their math and gets the wrong answer or did not do it the right way, it does not mean that they are trying to troll anybody.

Concerning the question about people giving no information or little to none, nobody knows except for the doer themselves. If you really want to help those people, you can still add your answer, EVEN if it already has multiple relpies.

Hope this helped!

I am assuming you mean "no two girls". Anyways, we see, that the only way for no girl to be together is if they sit BGBGBG or GBGBGB.

Therefore, we can do a premutation to see how many different ways this is possible. 

So:

2 * 3! * 3! = 72.

For this, we can make an inequality. So, here is what we have, according to the question:

2 sacks of sugar + 3 sacks of flour \(\leq\) 40 lbs

flour \(\leq\) 2 sacks of sugar + 6lbs

Using variable form, this is:

2s + 3f \leq 40

f \leq 2s+6

Since the question is asking for the largest possible weight, we can change the /leq to equal signs

2s + 3f = 40

f = 2s+6

Now, we can isolate the two stacks of sugar. So:

f-6 = 2s

40-3f = 2s

Now, our equation is:

f-6=40-3f

4f=46

f = 11.5 lbs

Therefore, the flour weighs 11.5 lbs.

Thanks for the answer! Just wondering, (this may be a glitch) do you see more than one post on this? It says that there are 3 replys, but only one post has shown up.

To do this, we first need to expand the equation. This will be : 

8a+12=20

Subtracting 12 from both sides, we get:

8a=8

Divide both sides by 8, and we get:

a=1
