In response to geno3141 (Idk how to reply to your comment. Sorry)

I do know how to finish from there, but as of my understanding, I needed to do:

+ and +   

+ and -

- and -

- and +

You gave me only these solutions:

+ and +             

+ and -

Could you explain why?

The fastest method looks like "elimination," where you line the equations up and add straight down.

5x + 7y = -11

5x - 3y = 19

If we added straight down right now, that would give us 10x + 4y = 8, which doesn't help any. We want one of the variables to go away.

Multiply the top equation by negative one all the way through.

(-1)(5x + 7y) = (-1)(-11)

-5x - 7y = 11

Now line up both equations and add straight down:

-5x - 7y = 11

5x - 3y = 19    

0 - 10y = 30

-10y = 30

y = -3

Plug in y into either one of the equations to find x:

5x - 3(-3) = 19

5x + 9 = 19

5x = 10

x = 2

6075 / 4050  =  2/3

4050 / 2700  =  2/3

2700 / 1800  =  2/3

Find  2/3  or 1800  for the next term; then find 2/3rds of that answer for the next term, etc.

A monomial has only one term (letters and variable multiplied or divided together); terms are separated by addition or subtraction.

Therefore:  s + 3  is a binomial (two monomials separated by addition).

|3x - 1|  =  |2x + 6|

Either     3x - 1  =  2x + 6     or     3x - 1  =  -(2x + 6)

Can you finish it from here?

The answer is 20.4m

The additive inverse of -4 is 4 . (I think this is the one you want.)

The mutliplicative inverse, or reciprocal, of -4 is -¼ .

The negative reciprocal of -4 is ¼ .

That's all I can think of :)

1.516  =  sqrt (60 * W / 3131)      square both sides

1.516^2   = (60/3131) W      multiply both sides by 3131/60

(3131/60)1.516^2  = W    ≈ 119.93 lbs

That would be 6x²-12x

Surface area  =  2 [ 8*2.6 + 8*4 + 4*2.6]   = 126,4 m^2

Hi Tetre :)

\(\dfrac{2027!+2028!}{2028!-2029!}\\ =\dfrac{2027!+2027!*2028}{2028!-2028!*2029}\\ =\dfrac{2027!(1+2028)}{2028!(1-2029)}\\ =\dfrac{2027!(2029)}{2028!(-2028)}\\ =\dfrac{(2029)}{2028(-2028)}\\ =\dfrac{-2029}{2028^2}\\\)

-2029/(2028*2028) = -0.000493339791246

19+24=43crackers

[ 2027! + 2028!]  / [ 2028! - 2029! ]

Note that we can write this as

[ (2027!) (1 + 2028) ]  / [ (2027!) ( 2028 - 2028*2029) ] =

(1 + 2028) / [ 2028 ( 1 - 2029)]

(2029) / [ 2028 (-2028)] =

-(2029) / 2028^2  =

-2029 / 4,112,784

Hey!! Glad you could join!! Nice username, haha 

So i updated google chrome and now it works so yay 

-person who wasnt able to make an account before but i now can so ayylmao also im not the author of the post xD

Area  = (1/2)pi *(diameter/2)^2  = (1/2) pi * (8/2)^2  = (1/2) pi * 4^2  = (1/2) pi * 16 =

8 pi units^2   ≈ 25.13 units^2

Yes, just do a thing called the X game.

The X game is putting an X on your paper.

Since the expression is always in order like x^2, x, then a number. Your first term is A, your second is B, and the third is C.

Multiply A and C, then put the sum of that in the top part of the X. Next, take your B and put it in the bottom of the X. You'll now have the left and right side blank. These two spots will be your factored out answer. You need to find two numbers that can be multipied to get the number in the top part of the X, while making sure these two combined equal the amount in the lower part of the X. In this case since the top is 12 and the bottom is -7; the two numbers that would fill the left and right sides are -4 and -3. After you find the two, put your starting variables with the numbers like this: (x-3)(x-4) Easy dood. Wish I could've drawn it for you. You're Welcome.

Hi Melody!

Next to us in the park is a lonely donkey. He's called Neddy and is my favorite animal.
Thank you for the wonderful pictures of the Australian Galah.
Love greetings, asinus :- )

6x⁴y² - 4x²y + 2xy² + 8

Ascending means from least to greatest.

8 - 4x²y + 2xy² + 6x⁴y²

The last two terms have the same power of y, so I guess it doesn't matter which comes first.

Also the normal way to arrange an expression is to put the powers in descending order, which just means from greatest to least.

What FirstLast said is true, x > 9.

Also, since it is the absolute value of 10x+15,

the other option is:

10x + 15 < -105

10x < -120

x < -12

x > 9     OR    x < -12

.913 = 913/1,000

122=(7a)/2

*2           *2

244=7a

/7     /7

244/7=a

For those who are being "thrown" off when they're supposedly logged in.....this happened to me at my local library.....I found that the rememdy was to access the site using Google Chrome.....I don't know whether this will work for you, bur it might be worth a shot.....
