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.

4x2-7x-15
(4x+5)(x-3)
If [ y = 3 + x ],
then [ x = y - 3 ].
That's all you can tell with the given information.
If you want to know what 'x' and 'y' are, you need one more equation.
What does e equals mc spared mean?
Unless this is a joke, I think you mean squared.
e = mc2 is a famous equation by Albert Einstein. Probably the most famous equation of the 20th century. E stands for energy, m for mass and c for the speed of light (a "c" because the speed of light in a vacuum is a universal constant). Amongst other things it tells us that mass is equivalent to energy, and that a small amount of mass can provide a huge amount of energy.
If you are interested just search on the Internet, or in a science book, for "special theory of relativity".
What is two x plus sevensixths equals three x minus sevensixths?
2x + 7/6 = 3x - 7/6 : subtract 2x from both sides
7/6 = x - 7/6 : add 7/6 to both sides
14/6= x : for presentation purposes make 'x' the lead term
x = 14/6 = 22/6 = 21/3
Write an equation for 12 groups of 12?
12x12
OR
12+12+12+12+12+12+12+12+12+12+12+12
if in a problem it would be something like this
there are twelve bubblegum pieces,
in a pack of 5 gum (i dont remember if its that much)
and i bought twelve packs to have >.> so much~
how many pieces do i have ;3
just like that
Can you solve for a variable in an equationWhy?
YOU CAN SOLVE FOR A VARIABLE IN AN EQUATION, BUT NOT AN EXPRESSION.. FOR EXAMPLE: RIGHT WAY: 4u+6=26
-6 -6
So you are left with 4u=20
now you divide the 4u by 4 because you want to do the
opposite of multiplying. also, you divide the 20 by 4.
So... u=5
How much fabric to cover 36 x 2 x 4?
You don't say what units you're using for the measurements - However, the answer is 288 units (whichever you use)
What is 2 out of 3 plus 3 out of 8?
When adding or subtracting Fractions you need "A Common Denominator (The Denominator is the bottom number and Numerator is the top) "
For example 3 and 8 are the denominators and they both go into 24, so you would do 3x8=24 and 8x3=24
Then what ever you do to the bottom you do to the top
2x8=16 and 3x3=9
The question would be 16/24 + 9/24
When adding you do not change the denominator ,but you add the numerator. The answer would be 16/24 + 9/24 = 1 and 1/24
What is 2x plus 1 divided by x minus 5 less than or equal to 3?
(2x + 1) / (x - 5) <= 3
Multiply both sides by (x-5):
2x + 1 <= 3(x - 5)
Expand the right side to eliminate the parentheses:
2x + 1 <= 3x - 15
Add 15 to each side:
2x + 16 <= 3x
Subtract 2x from each side:
16 <= x
There you have it. 'x' must be at least 16.
What is the inverse function of f of x equals 1 pls answer need to teach it tomorrow?
'Telling' it is not 'teaching' it.
Pls, for the sake of your students, ask someone who understands it to come in and teach it,
just in case any of the students have questions.
