Calculus

It is called a function.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. The second line is, in fact not a line because all you have is an expression, not a equation.

Depending on where the equality sign appears, the two lines could intersect at right angles of not.

It is not a linear function because it is missing x as the input variable

A tangent is a straight line and so is of infinite length. There is nothing in the question to suggest otherwise so the answer is simple: a tangent is of infinite length.

Depends on size and level of protection

x2 + y2 = r2

Where "x" and "y" represent the co-ordinates of any point on the curve relative to it's center point, and "r" represents it's radius. If you want to specify a curve that goes around a specific point (we'll call it {a, b}), then that can be expressed as:

(x - a)2 + (y - b)2 = r2

That depends on how fast you can count.

The natural log of a number is some other number such that if you take e (2.718281828...) and raise it to that other number you would get the first number. Another way to say this is that a natural log is a log with base e.

The common log of a number is some other number such that if you take 10 and raise it to that other number you would get the first number.

The natural log base, e, is a special transcendental number, chosen so that the derivative (respect to x) of ex is equal to ex . In other words, the slope of a tangent line to the curve y = ex at point (x, ex) is equal to ex for all x

There is no simple factorisation because the quadratic expression does not have rational roots. Irrational roots are not used in factorisation.

If it's moving in a curve or some other non-straight path, then yes.

If it's moving in a straight line, then no.

Let me assume that this equation is -2 -8x = 40

It's usually best to move all the purely numerical items to one side first. Let me move the -2. Then, to do this I add 2 to both sides.

-2 - 8x +2 = -8x = 40 + 2 = 42 or -8x = 42

Now, to yield x 'by itself' let me divide both sides by -8.

(-8x)/-8 = x = 42/(-8) = -21/4 or x = -21/4

well you first get the 43 and take away 3 to make it 40, then you divide it by 8 to give you 5 so thats how 2x becomes 5x. Then you add 2 x 5 which = 10 then you add the 3 that was taken away from the 40 so you come out with the solution of: 2x + 43 = 5x + 13.

y-x is an expression, not an equation. Therefore, the question does not make sense.

well, i believe it goes like this (not certain)

An infinite number. Each solution is a pair of numbers that makes a true statement

when they're stuck in place of 'x' and 'y'.

Any pair of numbers will do it, just as long as the 'y' number is one more than double the 'x' number.

Yes, it is the only solution.

I don't need to break "4 x 5" apart, because just as it is, "4 x 5" is a multiplication fact

that I know. If you start doing your own work, you'll know it too, in almost no time at all.

I assume you mean this system.

Y - 4X = 10
Y = 2X - 6

You are given Y, so insert into top equation to find X.

(2X - 6) - 4X = 10

- 2X - 6 = 10

-2X = 16

X = - 8
===========find Y, bottom equation

Y = 2(- 8) - 6

Y = - 16 - 6

Y = - 22
============ You try checking it.

Log(y) can be any number, positive or negative, no limits.

It all depends on the value of 'y'.
