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 of -2x plus 4greater than12?
What you want to do is get x by it self so to do that you must do two things: First you must minus 4 from both sides -- so now you have -2x greater than 8. Second you must divide by -2 however if you multiply or divide by a negative number in a greater than or less than equation then you must flip the sign -- thus you end up with x is LESS THAN -4. -2x + 4 > 12
-2x + 4 - 4 > 12 - 4
-2x > 8
-2x/-2 < 8/-2
x < -4
How do you write x equals one half y in general form?
x= y (1/2) or x= y/2 or x= y times 1/2 or x= 1/2y
No.
Remember: sin2 + cos2 = 1
So, in place of (1 - 2 sin2) we can write (sin2 + cos2 - 2 sin2).
Massage that around slightly: (sin2 + cos2 - 2 sin2) = cos2 - sin2
That's not equal to (sin2 - cos2), which is the original question we were asked.
What does x equal in 3x plus 9 equals 54-2x?
3x + 9 = 54 - 2x
Subtract '9' from both sides
Hence
3x = 45 - 2x
Add '2x' to both sides
5x = 45
Divide both sides by '5'
x = 9 The answer!!!!!
Verification
3(9) + 9 = 27 + 9 = 36
&
54 - 2(9) = 54 - 18 = 36
Hence both sides are equal at '36'.
Does light from the sun travel at 186282 miles per second?
Yes. And it takes about 8 1/2 minutes for it to reach the earth.
What is the answer to 6y-2 equals 2y plus 18?
6y - 2 = 2y + 8 : Subtract 2y from both sides
4y - 2 = 8 : Add 2 to both sides
4y = 10 : Divide both sides by 4
y = 10/4 = 2.5 or 21/2
Who found the secrets of infinity?
Cantor found some of them. Specifically, he proved that certain infinities were greater than others.

What is the answer to -16 plus 7?
The answer is -9. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
How long would it take to earn 258 billion while working in a normal job?
Let's define a normal job by a job giving you a "normal" salary, for example the medium salary. In France it's €20 841 after-tax so you will need 12 379 444 years (if you don't spend any cent), about 154 743 lifes, to have in your pocket €258 billion
-1 = x + 9
Subtract 9 from both sides of the equation: -1 - 9 = x + 9 - 9
so -10 = x
-3y+5=-4 subtract 5 from each side of the equation: -3y=-9 Divide by -3 to get the variable alone:
y=3
What is 10.99 x 5 and 2 thirds?
(10.99) x (5 2/3) = (10.99) x (17/3) = 186.83/3 = 62.27666 (rounded, repeating)
How do you solve the equation 81t3 - 81t equals 0?
You factor it.
81t3 - 81t = 0
Divide by 81:
t3 - t = 0
Take out the common factor t:
t (t2 - 1) = 0
Here we have a difference of two squares, therefore:
t (t + 1) ( t - 1) = 0
If the product is zero, that means that one of the factors must be zero, so you have to solve the three equations:
t = 0 OR t + 1 = 0 OR t - 1 = 0.
In summary, t can be 0, -1, or 1.
What mistake do people make to solve for 1 equals 2?
Most people who believe that 1 = 2 make the mistake of dividing by zero:
If 1 X 0 = 2 X 0,
then you might suppose that 1 = 2, by cancelling the common factors, namely the factor of zero.
But you would be *absolutely* wrong to think this.
If it were correct, then all numbers would be equal. That would probably suit the Ministry of Education very well; not to mention the teachers' unions, as well as some nihilist philosophy students. But the bankers will never have it, and, so, the Indiana state legislature is in no danger of passing it. At last report, Indiana has not legislated the value of pi, either.
