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.

How do you simplfy 3x plus 2y plus 5x plus y?
By rearranging and combining similar terms. For example, 3x + 5x = (3+5)x = 8x.
How do you make the infinity sign?
If you have a Mac then press (alt) option then 5. ∞ is what you get. If you have a PC then I can't help you.
if you have a PC then copy the sign from the internet, go onto word and then control autocorrect options, then where it says replace / with, paste the infinity sign into the 'with' bar, and put whatever you want in the 'replace' bar. Click OK. when you type what you typed in the 'replace' bar into word, it will automatically turn into the infinity sign.
If you have a PC, just hold down ALT and press 2 3 6 and release ALT VOILA!! ∞∞∞∞∞∞What quadrant will the area be if x equals and greater than 0 and y equals and less than 0?
Quad IV
x is right side, y is down.
How does the length of a pendulum affect the frequency?
A longer pendulum will have a smaller frequency than a shorter pendulum.
How do you solve c2-4c plus 4 equals 0?
C2-4c+4=0
(c-2)(c-2) c-2=0 and c-2=0
C=2 and c=2
Put 2 in place of c and solve the equation
Is y equals x plus 4 a linear function and why?
Yes. y + x = 4 is a linear function because the highest order (exponent) on any dependent or independent variable is 1. So if it were y^2 + x = 4 or y + x^3 = 4 or yx + 4 = 0 or anything like that, it would be non-linear. If that doesn't help, if you rearrange y + x = 4 into standard y = mx + b format you get y = -x + 4. So it's a straight line with a slope of -1 and y-intercept of 4. Any time you have an equation that just has the letters in it (x, y, z, etc. any letter) without any exponents, it's a linear equation.
I'm pretty sure it's undefined meaning it is a vertical line.

No, it is not. It is a horizontal line, 1 unit above the x-axis. Its slope-intercept equation can be written as y = 0x + c : that is, slope = 0, intercept = 1.
X raised to the 2 power plus 9 equals 6x?
So x2 - 6x + 9 = 0, Factorises as (x - 3)(x - 3) so only solution is x = 3
What is x plus y equals 2 and x plus 2y equals -10?
I suppose the full question is:
Given the following system of equations, find the values of x and y.
x+y=2
x+2y=-10
First, you need to isolate the variable y in the equation x+y=2
You do this by subtracting x from both sides of the equation.
x+y-x=2-x
Simplify:
y=2-x
Now you substitute the equation 2-x in the place of y in the equation x + 2y=-10
Like this:
x+2y=-10
x+2(2-x)=-10
Distribute the two:
x+4-2x=-10
Combine like terms:
-x+4=-10
Subtract 4 from both sides:
-x+4-4=-10-4
Simplify:
-x=-14
Divide both sides by negative one to get rid of the negative sign in front of x:
-x/-1=-14/-1
Simplify:
x=14
Plug the value of x (14) into the equation x+y=2:
14+y=2
Subtract 14 from both sides:
14-14+y=2-14
Simplify:
y=-12
Now you are done.
From now on, please pay attention in class.
If you don't even know the basic math skills that this requires then you have no future.
How do you figure out 87 raised to the x equals 0.5?
87^x = 0.5
take the log of both sides:
log(87^x) = log(0.5)
according to one of the log laws, you can move exponents to the front of the log function, so:
x(log87) = log(0.5)
so, then you have to get x by itself, so divide...
x = log(0.5)/log(87)
x= -0.1552
so, to prove this:
87^(-0.1552)= 0.499997
(Close enough, I just rounded in the middle, but this answer would be more than acceptable)
Solve for the missing number - 2 over x - 5 equals 4 over x plus 2?
-2/(x-5) = 4/(x+2) (from this step you have to cross multiply)
-2(x+2) = 4(x-5) (use the distributive property)
-2x - 4 = 4x - 20 (add like terms)
-6x = -16 (divide)
x = 8/3 (answer)
