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.

What is the answer to 2x2 plus 10x plus 12x plus 3?
2.2+10.x+12.x+3
=4+10.x+12.x+3
=22x+7
This is assuming you just needed to simplify. The "." are just multiplication signs.
What does x equal in the equation 8 multiply x minus 4 equals 3 multiply x plus 1?
It depends.
If you meant 8x-4=3x+1 then:
5x=5
x=1
But if you meant 8(x-4)=3(x+1) then:
8x-32=3x+3
5x=35
x=7
What is the y-value of x equals -3?
y is all real numbers at x=-3. On a graph it would look like a vertical line parallel to the y axis that goes from negative infinity to infinity passing through the x axis at -3.
What is the solution set of x plus 1 divided by 10 equals -3 divided by 5?
(X + 1)/10 = -3/5
take the extreme mean; cross multiply
-30 = 5(X + 1)
distribute on right
-30 = 5X + 5
subtract 5 from each side
-35 = 5X
divide each side by 5
-7 = X
check
(-7 + 1)/10 = -3/5
-6/10 = -3/5 same thing, checks
Find general solution of x to power of 3 dp divided by dx equals a minus x?
I can't integrate a-x /x-3 ?
The simultaneous equations are: 3x -y = 5 and 2x^2 +y^2 = 129
If: 3x^2 -y = 5 then y^2 = 9x^2 -30x +25
If: 2x^2 +y^2 = 129 then y^2 = 129 -2x^2
So: 9x^2 -30x +25 = 129 -2x^2
Transposing terms: 11x^2 -30x -104 = 0
Factorizing the above: (11x -52)(x +2) = 0 meaning x = 52/11 or x = -2
By substituting the above values into the original equations the points of contact occur at (52/11, 101/11) and ( (-2, -11)
What is the derivative of x to the power of e?
e^[ln(x^2)]=x^2, so your question is really, "What is the derivative of x^2," to which the answer is 2x.
What is the ordered pair of y equals 3x plus 2 y equals x plus 12?
y = 3x + 2
y = x + 12
You're looking for the point where the graphs of those two equations intersect.
At that point, the x-values of both lines are the same, and their y-values are the same.
Since the y-values are the same,
3x + 2 = x + 12
Subtract x from each side of the equation:
2x + 2 = 12
Subtract 2 from each side:
2x = 10
Divide each side by 2:
x = 5.
Substitute [ x = 5 ] back in either one of the original equations:
y = x + 12
y = 5 + 12
y = 17
The intersection point is (5, 17) .

Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared". It is not possible to make sense of the equation that you are referring to.
What are the order pairs for x plus y equals 8 and 2x equals y - 5?
The answer is - not are : (1, 7).
Probably not but it is impossible to be sure because, unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).

How can you find th discriminate of a function?
Discriminant = b2 - 4ac
A positive answer means two real roots, a 0 answer means one real root and a negative answer means no real roots. Example
X2 + 3X - 10 = 0
a = 1
b = 3
c = -10
32 - 4(1)(- 10)
= 49
----------------a positive answer telling you this quadratic function has two real roots.
What formula can be used to find 2x - 5 and 5x - 1?
You don't need a formula. All you need is the value of 'x'.
