As of October 11, 2011, the record for the computerized listing of the numbers of Pi is some 10 Trillion. See the link below for more on the subject.

It might be easier to calculate using numeric values directly if the equation is really simple.

An integral plow is one in which the entire weight is carried by the three point hitch when transporting and it may or may not have a tailwheel and gauge wheels, a semi-integral plow has a wheel or wheels that remain in contact with the ground when transporting while the rest of the weight is carried by the three point hitch, a drawn plow is self supported on wheels and is attached to tractor solely by the drawbar.

y = 6 - 4 = 2, thus 3y = 3 x 2 = 6

The points on the line y + .5x are all the points of the form (x, y) that satisfy the equation y + .5x = 0.

This is a standard form linear equation, where y is the dependent variable and x is the independent variable. The equation y + .5x = 0 can be rewritten as y = -.5x. This is the slope-intercept form of the equation of a line, where the slope of the line is -.5 and the y-intercept is 0.

Thus, the line y + .5x is a line with a slope of -.5 and a y-intercept of 0. All the points on this line have an x-coordinate that satisfies the equation y + .5x = 0.

0.196 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 196/1000 which simplifies to 49/250.

1. Whenever you divide a number by itself, the answer is 1, except when dividing by zero.

Without further information, "y" can have any value.

y = 8

9 + x > 6

NB Treat the inequality like an 'equals' sign. There are two exceptions; they are when using fractions or dividing by negative numbers.

9 + x > 6

Subtract '9' from both sides

x > 6 - 9

x > -3

Verification ;

When x = -4

9 + - 4 = 5 < 6 ( Not true

When x = -2

9 + - 2 = 7 > 6 (True)

YES!!!!

Sin(2x) = Sin(x+x')

Sin(x+x') = SinxCosx' + CosxSinx'

I have put a 'dash' on an 'x' only to show its position in the identity. Both x & x' carry the same value.

Hence

SinxCosx' + CosxSinx' =

Sinx Cos x + Sinx'Cosx =>

2SinxCosx

NO!!!

x^2 + 1 = x^2 + 1^2 . This does NOT factor!!!!!

Remember , two squared terms with a positive between them, does NOT factor. However, two squared terms with a negative between them does factor.

e.g.

x^2 - 1^2 = ( x + 1)(x - 1) Note the change of signs inside the brackets.

So taking the Pythagorean equation ; a^2 + b^2 = c^2,, this does NOT factor. However, algebraically rearranging we have a^2 = c^2 - b^2 does factor to

a^2 = (c - b)(c + b)

'x' is a fixed but unknown amount. It is not a VARIABLE!!!!

From the information given the circle centre is (-4,3).

Since no sign is given with '4' , it is assumed it is positive.

The '= 4' is radius squared (Pythagoras).

So the whole equation becomes

(x --4)^2 + (y - 3)^2= 4 = 2^2 =>

( x + 4)^2 + ( y - 3)^2 = 2^2 (Note the Pythagorean equation).

Multiply out

x^2 + 8x + 16 + y^2 - 6y + 9 = 4

Collect terms

x^2 + y^2 + 8x - 6y + 21 = 0

The equation of the given circle.

x/7 = 2

Multiply both sides by '7'

7x/7 = 7 x 2 = 14

On LHS cancel down '7'

Hence x = 14

x = 13/11 & x = 17/19

Hence

x - 13/11 = 0 & x - 17/19 = 0

We now form a quadratic equation from these two linear equations.

(x - 13/11)(x - 17/19) = 0

Using FOIL multiply out.

F(First ; x X x = x^2

O(Outside) ; x X -17/19 = -17x/19

I(Inside ; -13/11 X x = -13x/11

L(Last ; -13/11 X -17/19 = (+)221/209

Hence the equation becomes

x^2 - (17/19 + 13/11)x + 221/209

Add the fraction in 'x'

x^2 - 434x/209 + 221/209 = 0

This is the quadratic eq'n. However, we can remove the denominator of '209' by multiplying through;-

209x^2 - 434x + 221 = 0

The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph

you subtract x from both sides for both equations to get it in y= form. so...

x+y=5

x+y-x=5-x

y=5-x

x+y=6

x+y-x=6-x

y=6-x

thanks:D but i meant with absolute value signs it was supposed to look like this : |x+y|=5 and |x|+|y|=6 ... but when i typed it in answers.com changed it

It is a binomial algebraic expression.

Its value can be evaluated if x is known.

y=54 if x=6

so we can write

y=9(x)

so y=k(x)

clearly y is directly proportional to x.
