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 solution of subtract 5x2 - x 7 from the sum of x3 x2 x - 2 and 2x3 - 3x2 2x - 5?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2).
What is the answer to 25x-2y plus 13x-6y plus x?
There can be no answer because the question contains an expression, not an equation or inequality.
Is a gram the same a a cubic centimeter?
No, it is not. A gram measures mass (like ounces or pounds), and a cubic centimeter measures volume (like cubic inches or quarts). They do not measure the same kind of value.
Take the exponent and multiply it by the coefficient (or 1 if there is no coefficient) then subract 1 from the exponent.
For example, the derivative of 2x^3 is 6x^2
If there is no exponent, for example, 2x the derivative is 2 because the exponent is actually 1 which produces the same coefficient and the exponent 0 meaning there is no x.
What is 7x plus 6 equals 41 what is x?
Here is the work for that problem.
7x+6= 41
7x=41-6 (subtracting 6 from both sides)
7x=35
x=5
What is the solution of y equals x plus 2 and negative 5x plus 6y equals 15?
y=x+2 -5x+6y=15
You use the substitution property to plug y into the 2nd equation
-5x+6(x+2)=15
Then, you solve the equation
That should leave you with x=3
Then you plug that into the first equation, and that should leave you with a final answer of
x=3 and y=5
What is 1 fourth plus y equals x what equation would be solved in this?
That statement itself is an equation, and there are an infinite number
of (x, y) pairs of numbers that satisfy it.
To draw a graph of the equation, draw a straight line that rises toward the
right at an angle of 45° and passes through [ y = -1/4 ] on the y-axis.
The x-value and y-value of every point on that line satisfy your equation.
(And we all know how many points there are on a line. Particularly on a line
that has no ends.)
What the solution of 2x plus 5y equals 16 and 2x plus 3y equals 14?
2x + 5y = 16
-2x - 3y = -14
2y = 2
y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
What is the simplest form of the expression w plus 2x plus 3w - 2xw?
w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
4x+7=25-5x
(subtract 4x from each side to isolate the variables)
7=25-x
(add 25 to each side to get the numbers on the opposite side or the variable)
32=-x
(divide or multiply both sides by -1 to make the x positive)
x=-32
