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 value of 2x3 plus 15yif x equals -7 and y equals 2?
x = -7, y = 2
⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2
= 2 x (-343) + 15 x 2
= -656
-4 x 10 = -40 (Negative x Positive = Negative) So just multiply it regularly and add the negative sign because one of the multiples are negative
What does the line x 3 represent in y equals 5 x minus 3 second power plus 4?
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", "times", "equals", "squared", "cubed".
How many solutions does the linear system -8x plus 2y equals 6 and -4x plus y equals 3 have?
Two solutions and they are:- x = 0 and y = 3
What is limit as x approaches 0 of sin 1dividebyx?
There is no limit. As x approaches 0, sin 1/x oscillates between -1 and 1 infinitely many times. This is considered a form of divergence.
Simplifying
5y + -1 = y + 9
Reorder the terms:
-1 + 5y = y + 9
Reorder the terms:
-1 + 5y = 9 + y
Solving
-1 + 5y = 9 + y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-1y' to each side of the equation.
-1 + 5y + -1y = 9 + y + -1y
Combine like terms: 5y + -1y = 4y
-1 + 4y = 9 + y + -1y
Combine like terms: y + -1y = 0
-1 + 4y = 9 + 0
-1 + 4y = 9
Add '1' to each side of the equation.
-1 + 1 + 4y = 9 + 1
Combine like terms: -1 + 1 = 0
0 + 4y = 9 + 1
4y = 9 + 1
Combine like terms: 9 + 1 = 10
4y = 10
Divide each side by '4'.
y = 2.5
Simplifying
y = 2.5
Give the six trigonometric function of 120?
sin(-120)=sqrt(3)/2
cos(-120)=-1/2
tan(-120)=-sqrt(3)
csc(-120)=2/sqrt(3)
sec(-120)=-2
cot(-120)=-1/sqrt(3)
x+y = 8
-x+2y = 7
Add both equations together:
3y = 15
Divide both sidea by 3 to find the value of y:
y = 5
Substitute the value of y into the original equations to find the value of x:
Therefore: x = 3 and y = 5
What is the derivative of f of x equals 1?
f(x)=1
f'(x)=0 because the derivative of a constant is ALWAYS 0.
Is 3 a solution of 4x plus 2 minus 3c equals negative1 plus 6?
Since your equation has two variables in it ( 'x' and 'c' ), a "solution" is a number for each of them
that makes the equation true.
Sure, if you want 'x' to be 3, I can figure out what 'c' has to be.
And if you want 'c' to be 3, then I can figure out what 'x' has to be.
But the "solution" is a pair of numbers that tells you what they BOTH have to be.
And in order to figure that out for two variables, you need two equations.
What is y²-12y plus 36 equals 9?
y^2 - 12y + 36 = 9
subtract 9 from each side
y^2 - 12y + 27 = 0
easy factoring by inspection
(y - 3)(y - 9)
y = 3
y = 9
How do you solve the equation 6x-3x plus 8 equals x-9 plus 17?
6x-3x+8=x-9+17 -write out the equation
3x+8=x-9+17 - bring whole numbers to the right by subtracting it from
-8 -8 both sides if it is positive. If it is negative, add it to both
______________ sides
- Bring variables to left by repeating the same steps as the
3x=x-9+9 steps taken for the whole numbers.
-x -x - divide your whole number by the coefficient or multiply by 2
_________
2x=-9+9
2x=0
x=0
How do you solve 2x plus 3 equal 9 X equals?
The equation is 2(x) +3= 9. X would equal 3. The equation would now look like this, 2x3+3=9.
M divided by X is M/X, except when X is zero, in which case it is invalid. Other than that, since insufficient information was given in the question, no other answer can be given.
