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.

ok well first you have to use order of operations: first multiply then subtract, let me know when you get an answer!!
Hope this helps!!
How do you solve x2-81 equals 0?
2x - 81 = 0
Add 81 to both sides.
2x - 81 + 81 = 0 + 81
Substitute, -81 + 81 cancels out.
2x = 81
Divide by 2.
x = 40.5
Above answer would be correct if your question was 2x but it was x2 so using the same method you would get
x2 = 81 here the opposite of the square is the square root
x = 9
(1) M+B=2*J
(2) M=8+B
(3) J+B=20
Three equations. Three unknowns.
Rewrite (1)
M=2*J-B
Sub into (2)
2*J-B=8+B
Solve for B
2B+8=2J or B+4=J
Sub J into (3)
2B + 4 = 20
B = 8
J = 12
M=16
How do you solve this -52x plus 3 equals 7?
-52x + 3 = 7
-52x + 3 = 7
-3 -3
-52x = 4
/52 /52
-x = 1/13
/-1 /-1
x = -1/13
There are more than 1 set of values that will work. The value's of "x = 1" and "y = -1.5" will work and therefore the values "x = 100" and "y = -150" will work as well. In other words take any number you want for the value of x and multiply that number by negative 1.5 (-1.5) to get the value of y.
y = (x multiplied by -1.5)
20x-3 plus 3x equals 11x plus 5-8?
20X - 3 + 3X = 11X + 5 - 8
put those like terms together on the left
23X - 3 = 11X + 5 - 8
like terms together on the right
23X - 3 = 11X - 3
this equation admits of no solution, so is not true
X would = 0
How is this equation solved x plus 2 equals -2x plus 2?
x + 2 = -2x + 2
Add 2x to each side of the equation:
3x + 2 = 2
Subtract 2 from each side:
3x = 0
Divide each side by 3:
x = 0
The equation is a true statement only if x=0.
What is the inverse of y equal the log of 2x?
y = log 2x → x = 1/2 <base of log>y
So:
y = log102x → x = 1/210y (common logs)
y = loge2x → x = 1/2ey (natural logs)
Which is the solution set for x2 - 4x 8?
x = 2 + 2i
x = 2 - 2i
where i is the imaginary square root of -1.
What is the value of the y coordinate of the solution to the system of equations x 2y9 and x-y3?
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).
It is not possible to tell what the equations are!
What are the steps needed to solve the equations.?
That really depends on the equation. In the simplest cases, you need to isolate the variable on one side - eliminate anything other than the variable, by doing the same operation on both sides. For example, if you have an "x + 3" on one side, subtract 3 on both sides, to remove the "3" from the left side.
If the coefficient of curvature Formula has a mathematical Proof and if yes What is it?
proof of theorem r'(t) x r''(t)
K(t) =
r'(t)3 proof of theorem r'(t) x r''(t)
K(t) =
r'(t)3
How do you approximate an integral using Simpson's Rule when 'n' is odd?
You can't. Simpson's Rule can only be used when N is even. This is because the formula is derived by summing the area under parabolas using three points, or two subintervals.
In 2x plus y what are the variables?
A variable is a number that isn't fixed, it can be anything. So in this situation x and y are the variables.
It is used to measure small volume of liquid to be added where needed .
