6- 3x=5x - 10x + 16      simplify

6 - 3x =  -5x + 16         add 5x to both sides, subtract 6 from  both sides

2x  = 10       divide both sides by 2

x = 5

27-y=34

thank you

y=x^2-x-2

The x coordinate of the vertex  =   -b / 2a        where b = -1   and  a   = 1     .....so....we have...

x = -b / 2a   = 1/ 2(1)   = 1/2

And the y coordinate  =

(1/2)^2 - (1/2) - 2  =    1/4 - 1.2 - 2  =  -1/4 - 2 =  -9/4

So.....the vertex =  ( 1/2, -9/4 )

-7x-6y=4

      x=-3+8 

x = 5

And

-7(5) - 6y  = 4

-35 - 6y  = 4     add 35 to both sides

-6y  = 39          divide both sides by -6

y =-39/6  =  -13/2

x = 5   y  = -13/2

(72 / 1) /  (1/3)   =

(72 / 1 ) * ( 3 /1 )  =

216 / 1  = 

216

(x+1)(x^2-2x+5)  =

   ( x^2     - 2x      +    5 )

             ( x  +    1 ) 

-------------------------------

   ( x^3  - 2x^2  + 5x        )

+ (            x^2   - 2x   + 5 )

-----------------------------------

x^3  -    x^2     + 3x    +  5

cos (theta)  = - sqrt(6)/3           theta lies in the second quad

x = -sqrt(6), y = sqrt( 9 - 6)  = sqrt (3)    so.....sin(theta)  = sqrt(3) / 3

(1) sin(2 theta)   = 2 cos(theta)sin(theta)  =  2[-sqrt(6)/3 ] [sqrt(3)/3]  = (2/9)[-sqrt(6)*sqrt(3)]  =

(-2/9)sqrt(18)  = (-2/9)sqrt(9 * 2)  = (-2*3)/ 9 * sqrt(2) =  [ -2sqrt(2)]/ 3

(2)  cos(2 theta)  = cos^2 ( theta) - sin^2(theta)  =  [6/9] - [3/9] =  3/9  = 1/3

(3)  sin (theta/2)  =  sqrt [ ( 1 - cos(theta)) / 2 ]   =  sqrt [ (1 - -(sqrt(6)/3) / 2 ] =

sqrt [ (1 + sqrt(6) / 3) / 2]   = sqrt [ (3 + sqrt(6)) / 6]    

(4) cos (theta/2)  = sqrt[ [ ( 1 + cos(theta)) / 2] = sqrt [ (1 -sqrt(6)/3)/2]  =

sqrt [ (3  - sqrt(6))/ 6)

its suppost to be (-1) instead of that 10 answer

You changed screensaver again?

You divide circumference by Pi, so we have:

37/Pi=11.78 cm-the diameter of the baloon

11.78/2=5.89 cm-the radius of the baloon

Volume=4/3 X Pi X r^3

V=4/3 X 3.141592 X 5.89^3

V=4/3 X 3.141592 X 204.336469

V=855.922.....cm^3-The volume of the baloon.

Simplify the following:
1/2--2-1

-(-2)  =  2:
1/2+2-1

Put 1/2+2-1 over the common denominator 2. 1/2+2-1  =  1/2+(2×2)/2-(2)/2:
1/2+(2×2)/2-(2)/2

2×2  =  4:
1/2+4/2-(2)/2

1/2+4/2-(2)/2  =  (1+4-2)/2:
(1+4-2)/2

1+4 = 5:

Simplify the following:
k^3/k^5

Combine powers. k^3/k^5 = k^(3-5):
k^3-5

Answer: | k^-2

3x - 5y = -20     subtract 3x from both sides  

-5y  = -3x - 20    divide through by -5

y = (3/5)x + 4

Circumference=Pi X Diameter.

Yes, it is.

what is 2 to the millionth power=2^1,000,000=9.90065622... X 10^301029

It is a very BIG NUMBER consisting of 301,030 digits long.

3x-5y=-20

-3x       -3x

-5y=-3x-20

/-5   /-5 /-5

y= -3/5x-20

rly easy... -4

\(x = {-20 \over 5} = -4\)

Using the ceiling function, we have..... [ 84 * 14  +  25 * 31] / 1000  = 1.951   .....so......we need 2  pallets

[The ceiling function rounds any non-integer answer up to the next integer ]

2*  ( - sqrt (15)/3) * ( -sqrt(6) /3)  =

(2/9) * sqrt (15 * 6)  =

(2/9) * sqrt ( 90)  =

(2/9) * sqrt (9 * 10)  =

(2/9)* sqrt(9) * sqrt(10)  =

(2/9) * 3 * sqrt(10)  =

(6/9) * sqrt(10)  =

(2/3) * sqrt(10) =

[2 sqrt (10)] / 3

5+(0.3)^2 =

5 + (3/10)^2  =
