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 significance of the x-value in a sine wave function?
The answer will depend on where, in the sine function, the x-value appears:
For example, its roles in
f(x) = sin(x), or
f(x, theta) = x*sin(theta) or
f(x, theta) = sin(x*theta)
f(theta) = sin(theta + x)
are quite different.
How many solutions are there to the problem x equals -5y plus 5?
Infinitely many.
The solution is a pair of numbers ... one number for 'x' and one number for 'y' ...
that makes the statement [ x = -5y + 5 ] a true statement.
There are an infinite number of those pairs.
The graph if this equation is a straight line, and every point on the line is a solution to the equation.
Here are a few of them:

-2 . . . . 15
-1.27 . . 11.35
-1 . . . . 10
0 .. . . . . 5
1 .. . . . . 0
2 . . . . . -5

What is the first function to have points in common with the domain of the second function?
If you want to compose two functions, you need the range of the first function to have points in common with the _____ of the second function.
How do you factor x2 -2x-8 using the quadratic formula?
X2 - 2X - 8 = 0
Quadratic formula.
X = - b (+/-) sqrt(b2 - 4ac)/2a
a = 1
b = - 2
c = - 8
X = - (- 2) (+/-) sqrt[(- 2)2 - 4(1)(- 8)]/2(1)
\
X = 2 (+/-) sqrt(4 + 32)/2
X = 2 (+/-) sqrt(36)/2
X = [2 (+/-) 6}/2
X = 4

with time
it sounds stupid
but people say it for a reason
if you feel like crying...cry
if you feel angry...let it out
over time it will get easier and you will not feel the pain
my ex beat me, i was 14-15 at the time, together for just over a year
time really does heal everything
Solve 2 bracket y plus 3 equals 22?
=> 2(y+3) = 22
{divide both sides by 2}
=> y+3 = 22/2 = 11
{subtract 3 from both sides}
=> y = 11-3 = 8
y = 8
What are the first 12847635475 digits of Pi?
haha, i figured it out in two minutes xD
it's okay, who would want to answer questions for a living anyway?
but I'll give you a clue: i put it in as a joke because i didn't think there's any way it was the right answer.
(you know what's really tragic is that a tween girl can figure out a question that is stumping adults all over the country.)
Are the fractions 43 and 21 equal or not equal?
well, if you mean 43/100 and 21/100, no. because obviously neither can be simplified any more. I am guessing you didnt mean hundredths. sorry
4x plus 1 equals 52x how do you solve this?
Subtract 4x from each side getting 1 = 48x so x = one forty-eighth
2x+3=9
Your question is what is X value.
2x+3=9
2x=9-3
2x=6
2/2x=6/2
x=3

How do you solve 2x-1 equals 7?
2x-1=7 1) add 1 to both sides: 2x=8
2) divide both sides by 2: x=4
4 is the answer
