Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

8x-y equals 31and 5x plus 3y equals 23?
3(8x-y = 31)
5x+3y = 23
Multiply all terms in the top equation by 3:
24x-3y = 83
5x+3y = 23
Add both equations together in order to eliminate y:
29x = 116
Divide both sides by 29 to find the value of x:
x = 4
Substitute the value of x into the original equations to find the value of y:
Therefore: x = 4 and y = 1
Who was the first successfully established English colony in North America?
The first established English colony in North America was Jamestown, Virginia. There were 13 original colonies in the United States.
Graph a few of them, and watch for trends! Anyway, I assume you are talking about polynomials; in the case you mention, the general tendency is for the graph to go from the top-left, towards the bottom-right.
If x equals 4 and y equals 8 then 3x plus 8y equals?
8x8 = 64 so it is 64 (the y)
3x4 = 12 so it is 12 (the x)
64+12 is 76.
5X-3 equals 12 what is the value of x?
5x - 3 = 12
Add 3 to both sides: 5x = 15
Divide both sides by 5: x = 3
What is the inverse of y equals 2x plus 3?
I presume you mean given y find x:
Make x the subject:
y = 2x + 3
=> 2x + 3 = y
=> 2x = y - 3
=> x = (y - 3)/2
which can also be expressed as:
x = 0.5 y - 1.5
What is the value of x if 3x-5 equals x 7?

The standard equation for an upward opening parabola with its vertex at (f,g) is (x - f)2 = 4c(y - g), where c is the focal length, that is the distance of the focus from the vertex.
Putting the equation shown in this form we have :-
(x - 3)2 = 4 * 1(y - 2) . . . thus c = 1
The vertex is at (3,2) and as the focal length is 1 (and this is positive) then the coordinates of the focus are (3, [2 + 1]) = (3,3).
What is x if 2x plus 5x equals 35?
=> 2x + 5x = 35
{collect x's}
=> 7x = 35
{divide both sides by 7}
=> x = 35/7 = 5
How do you work out y equals 4x?
You need to obtain the value of x and then multiply that by 4 to get the value of y.
What is the binomials is a factor of this trinomial x2 -5x plus 4?
x2-5x+4 = (x-1)(x-4) when factored
4x + 3 cannot equal 4x + 12:
- 4x + 3 = 4x + 12 (given)
- 3 = 12 (subtract 4x from both sides)
What is the solution of the equation 3x plus 17 plus 5x equals 7x plus 10?
3x + 17 + 5x = 7x + 10
Combine (add) the 'x'-terms on the left side of the equation:
8x + 17 = 7x + 10
Subtract 17 from each side:
8x = 7x - 7
Subtract 7x from each side:
x = -7
Which is smaller sin 0 or sin 200?
i think sin 200 is smaller than sin 0..
because sin 200= - sin 20..
sin 0 = 0
of course 0 > - sin 20
