x=-4.6

Very important!

I can. So there!

Not a great deal. Multiply it by itself and divide by 4. If x is imaginary, x2 is negative.

9x+18y = 36

18y = -9x+36

y = -1/2x+2 which is now in slope intercept form the slope being -1/2

x^2 + 13x + 30 = 0

x^2 + 10x + 3x + 30 = 0

x(x + 10) + 3(x + 10) = 0

(x + 3)(x + 10) = 0

x = -3 or x = -10

Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.

Pendulums have been used for thousands of years as a time keeping device in various civilizations.

Assuming that it is only displaced by a small angle, a pendulum wall have a period of 2pi*√(L/g) where L is the length of the pendulum and g is the acceeleration due to gravity, normally 9.81m/s².

One of the cool things about pendulums is that if one is made with a length of one meter, it will have a period of 2.00607 seconds, meaning it will take just slightly more than one second to swing from one side to another.

x ∈ C, x ≠ 0

Great !

There are an infinite number of pairs of numbers that (x,y) can be.

You can make a neat graph showing their relationship, and ... when you pick a number for 'x' or 'y' ...
showing you what the other one has to be.

On x-y graph coordinates, this equation is a straight line. It crosses the y-axis at the point [ y = 3 ],
and has a slope of [ -1 ] ... meaning that for every inch that 'x' increases, the line drops 1 inch lower.

One definition of sine and cosine is with a unitary circle. In this case, the sine is simply equal to the y-coordinate, and the cosine, the x-coordinate. Since the hypothenuse is 1, the equation in the question follows directly from Pythagoras' Law: x2 + y2 = r2, x2 + y2 = 1, cos2A + sin2A = 1. You can also derive it from the alternative definition of sine and cosine (ratios in a right triangle).

x is 5

y is 10

z is 15

5*5+14*10+5=

10+70+5=85

The y-axis is the metric of the dependent variable.

There you have two variables, x and y, so you need two independent equations in order to solve this. It cannot be solved without another equation.

For this problem, write it out... x-y=y... x=2y...8=2y...8/2=y...4=y

First, I made both y's on the same side( I added a y to both sides).

Then, I replaced the x with an 8.

Then, I divide out the 2 from both sides.

This leaves me with 4=y

So... x=8, y=4, 8-4=4

7x+3y=21

3y=21-7x

y=7-(7/3)x

on comparing with d eqn for a st line

y=mx+c where m= slope and c=y intercept

here m=(-7/3) n c=7

(0, -14)

It could be some kind of an algebraic expression.

When x = 0, y = 3. So mark the point (0, 3)

When y = 0, 4x = 3 ie x = 3/4 so mark the point (3/4, 0)

Join these two points with a line and extend in both directions.

Done!

Yes.
