All letters have rotational symmetry if you allow a rotation of 360^o.

The only letter in that group of have a rotation less than 360^o is the letter Z, which has rotational symmetry of 180^o.

Have  a great day everyone. :)

The formula for slope:  m  =  (y₂ - y₁) / (x₂ - x₁)

For this problem  (x₁, y₁)  =  (1, -19)   --->   x₁ = 1,  y₁ = -19

                            (x₂, y₂)  =  (-2, -7)   --->   x₂ = -2,  y₂ = -7

Placing these numbers into the formula:  m  =  (-7 - -19) / (-2 - 1)   --->   m  =  12 / -3   --->   m  =  -4

It's ok

I like the calculator

Arghhhhhhhhhhhhhhhhh!

mum just called me. Why can't I ever hav peace?!?!?

yeah I did did you? 

I gtg now I'll be back in a few hours and tomorrow if I don't catch you again today

Did you have a nice Christmas/ new year?

9x + 9  =  45 + 5x

First, get all the variables to one side by subtracting 5x from both sides:

9x - 5x + 9  =  45 + 5x - 5x

4x + 9  =  45

Now, get all numbers to the other side by subtracting 9 from both sides:

4x + 9 - 9  =  45 - 9

4x  =  36

Finally, divide both sides by 4:

4x/4  =  36/4

x  =  9

Hah, I hardly ever use this for math!

okay

yeah I wasn't on this sight much over vacation only reason im on now is because of math

If you can still talk go to the thing I posted at the top.

Solve for x: -27 x-38 x^2 = -25 Divide both sides by -38: x^2+(27 x)/38 = 25/38 Add 729/5776 to both sides: x^2+(27 x)/38+729/5776 = 4529/5776 Write the left hand side as a square: (x+27/76)^2 = 4529/5776 Take the square root of both sides: x+27/76 = sqrt(4529)/76 or x+27/76 = -sqrt(4529)/76 Subtract 27/76 from both sides: x = sqrt(4529)/76-27/76 or x+27/76 = -sqrt(4529)/76 Subtract 27/76 from both sides: Answer: | | x = sqrt(4529)/76-27/76   or    x = -27/76sqrt(4529)/76 

P.S. Please DO NOT use "e" as a variable, because "e" has a special meaning in Math.

-2(7 - n) + 4

First:  use the distributive property:  -2(7 - n)  =  (-2)(7) - (-2)(n)  =  -14 + 2n:

-14 + 2n + 4

Now:  add like terms:  -14 + 4  =  -10

-10 + 2n

Haha, I'm doing school, it's probably gonna be a few min till my mom calls me. Man I missed you the forum was soooooooooooooooo boring!

yay!!! but I think I just heard my mom say it's time to go. but I'll be on till we do go
