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 to 7x-9 equals 3x plus 5?
7x - 9 = 3x + 5
7x - 3x - 9 = 5
7x - 3x = 5 + 9
4x = 14
x = 14/4
How do you do y equals 2x plus 3 and y equals 3x plus 1?
Both equations are equal and so:
3x+1 = 2x+3
3x-2x = 3-1
x = 2 and by substituting y = 7
divide by 2 to give 3.5x = y
That is all you can do without further information about x.
What are the zeros of q(x) x(x - 3)(x 5).?
It is difficult to be sure because the browser used for posting questions is pretty much useless and strip out most mathematical symbols. Having made that clear, the answer is probably 0, 3 and -5.
Is 3 times 6 the same as 18 divided by 6?
No, no the answers 18 and 3differ by factor 6
3 x 6 = 18 (not 3) and
18 / 6 = 3 (not 18)
What is the solution of 5x plus 21-3x equals 97?
2x + 21 = 97
2x = 76
x = 38
Check it.
5 x 38 + 21- 3 x 38
190 + 21 - 114
211 - 114 = 97
It checks.
Is critical point also an inflection point?
no, a critial point is where the slope (or the derivitive) is 0. the inflection point is when the graph switches from concave up to concave down or vice versa
How do you solve 9X plus 7 equals 4X - 8?
Here are the steps:
-- Write the equation.
-- Subtract 7 from each side of the equation.
-- Subtract 4x from each side.
-- Divide each side by 5.
Why time periods is equal of pendulum?
A simple pendulum, ideally consists of a large mass suspended from a fixed point by an inelastic light string. These ensure that the length of the pendulum from the point of suspension to its centre of mass is constant.
If the pendulum is given a small initial displacement, it undergoes simple harmonic motion (SHM). Such motion is periodic, that is, the time period for oscillations are the same.
The maximum distance an object in simple harmonic motion moves from equilibrium is called the?
amplitude
What is X to the second power minus 25 simplified?
x2 - 25
This expression is the difference of squares. Thus:
x2 - 52
(x + 5)(x - 5).
variation
How do you solve 7r equals 3r-52?
7r (- 3r) = 3r - 52 (- 3r)
4r = - 52
4r / 4 = -52 / 4
r = -13
Is x2 equals y2 plus 7 a function?
Possibly. It is not standard to but a number after a letter (e.g X or Y), so I'm not sure if you mean
2x = 2y + 7, or
x^2 = y^2 +7 (Say, "X squared equals y squared plus 7).
Both of those are functions. But it is mathematically "bad grammar" to put the number after the letter, as it makes it unclear if you have missed off the ^ sign to indicate that it should be a power. If the question box does not let you enter a ^ symbol, write "squared", or "cubed", or whatever the power happens to be . :)
How do you solve for 8x-y equals 4 and 5x plus 3y equals 17?
A system? Try elimination
3(8X - Y = 4)
5X + 3Y = 17
24X - 3Y = 12
5X + 3Y = 17
-------------------------+
29X = 29
X = 1
-----------find Y
8(1) - Y = 4
- Y = - 4
Y = - 1
-----------check
By inspection one can see this is inconsitent
