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.

Solve X plus 11 equals X plus 5?
X + 11 = X + 5
If that is your question, then your answer is: Not Solvable.
This is because, if both sides are addition, than X would have to be two different numbers in order to get them the same. However, you can't do that, because in math a single letter represents the same number. X is just a replacement for a single number, it can't mean two different ones.
What is the difference in x - 3 and 3 - x?
x-3 is subtracting 3 from x.
3-x is subtracting x from 3.
If x is substituted with a number, then the order matters since it's subtraction. Say x = 4... 4 - 3 is very different from 3 - 4.
What is 3x plus 27 equals 12x-45?
3x+27=12x-45
Bring x to one side and the numbers to the other
45+27=12x-3x
72=9x
x=8
For any step you don't understand message me
X + 3 = 10.
X + 3 - 3 = 10 - 3
X = 7
Double check your solution.
X + 3 = 10
7 + 3 = 10
10 = 10
So X + 3 = 10 when X = 7.
What are the domain and range of y equals 12?
The domain would be (...-2,-1,0,1,2...); the range: (12)
What is the variable for 16x equals 6x plus 100?
16x = 6x + 100
(subtract 6x from both sides)
16x - 6x = 6x +100 - 6x
(Therefore)
10x = 100
(Divide both sides by 10)
10x/10 = 100/10
(Therefore)
x = 10
Answer: Value of x is 10
What is the answer to x plus y to 3rd power plus x minus y to 3rd power?
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3)
= 2x3 + 6xy2 = 2x*(x2 + 3y2)
How do you graph y equals 1over 3x -2?
choose different values for x. lets make it easy and pick 1, 2, 3.
eg, x = 1. therefore y= 1 / {(3) - 2} = 1/1 = 1. Your first point is 1,1.
x=2 therefore y = 1/3(2) - 2 = 1/4. next point is 1, 0.25.
And so on. You should get an inverse curve
What is the difference between sin x and sin -1 x .?
-- sin(x) is a number. It's the sine of the angle 'x'.
-- sin-1(x) is an angle. It's the angle whose sine is the number 'x'.
How do you solve x plus y equals 6 and -x plus 3y equals -2?
To solve the simultaneous equations:
- x + y = 6
- -x + 3y = -2
Add the two equations together to get:
(x + -x) + (y + 3y) = (6 + -2)
⇒ 0 + 4y = 4
⇒ 4y = 4
⇒ y = 1 (dividing both sides by 4)
Substitute this value for y in the first equation to get:
x + 1 = 6
⇒ x = 5 (subtracting 1 from both sides)
Substitute for x and y found in the second equation to check:
-x + 3y = -(5) + 3(1)
= -5 + 3
= -2 as required
Answer: x = 5, y = 1
Or (in coordinate form) the point (5, 1) is where the lines x + y = 6 and -x + 3y = -2 meet.
