another nonlinear system of equations question?
Q. okay i asked a question before and i realized i used two examples in which both equations y were the same, well for the rest of the questions on this assignment they're different, like. x^2+y^2=20 2x+4y=0 what would i have to do for that?

A. Here are the two equations: x^2+y^2=20 and x+2y=0 (always simplify) from the second, you get x=-2y Substitute it into the first and you get 4y^2+y^2=20 ... or ... 5y^2=20 ... or ... y^2=4 ... or ... y=2 | y=-2 If y=2 then x=-2*(2)=-4; and if y=-2 then x=-2(-2)=4 Therefore you have the two answers: (-4,2) and (4,-2)

Construct an example of a system of nonlinear equations...?
Q. Entire questions: construct an example of a system of nonlinear equations, consisting of a circle and a hyperbola, that has exactly two real-number solutions. Thanks in advance for anyone reading this and trying to help out.

A. Hmm. A hyperbola consists of two separate branches, opening outwards from its vertices. We can pick a hyperbola, and then choose a circle so that it just barely touches the two vertices of the hyperbola. For the hyperbola, one can use x^2 - y^2 = 1 The vertices of this hyperbola will be at (-1, 0) and (1, 0), so if we take a circle of radius 1 centered at the origin, it will just touch it in two points. So the system of equations x^2 - y^2 = 1 [hyperbola] x^2 + y^2 = 1 [circle] will work; these two curves intersect only at (-1, 0) and (1, 0).

Please help with my algebra homework!!!! It's about functions and linear equations.?
Q. I. What similarities and differences do you see between functions and linear equations? II. Are all linear equations functions? Is there an instance in which a linear equation is not a function? Support your answer. III. Create an equation of a nonlinear function and provide two inputs for your classmates to evaluate. IV. Find examples that support or refute your classmates answers to the discussion question. Provide additional similarities and differences between functions and linear equations. Challenge your classmates by providing more intricate examples of nonlinear functions for them to solve. I have read the book and even done research online and I am still not understanding! Please help me!!! Thank you!

Solve the nonlinear system of equations for real solutions?
Q. How do you do it? Like for example: y=x-10 x^2-y^2=100 how would i solve this? thank you <3
Asked by Torrr - Wed Jun 9 02:47:50 2010 - - 2 Answers - 0 Comments
A. The first equation is solved for y already, so we can just plug in x-10 for y in the second equation, and solve for x: x^2 - y^2 = 100 x^2 - (x - 10)^2 = 100 x^2 - (x^2 - 20x + 100) = 100 x^2 - x^2 + 20x - 100 = 100 20x - 100 = 100 20x = 200 x = 10 Now plug 10 in for x in the first equation, and solve for y: y = x - 10 y = 10 - 10 y = 0 So, the solution is x=10, y=0. I hope that helps! :)

Math Question Please Help!? Solving Systems of Nonlinear Equations--Algebra II?
Q. Okay, so I understood how to do this when I read over the section, and the examples made sense, then I get to the first problem, and don't have a clue how they got the answer that's in the back. I tried working backwards from their answer, and that didn't work either. Here's the problem: Solve: x^2+y^2 = 25 4x + 3y = 0 If you could explain the steps, I'd really appreciate it! I know that you have to solve it by finding x or y then substituting it into the other equation, but I cannot solve it...in their answer, the first equation they solved was the one on the bottom. Thanks for your help!

How can I know if an equation is linear or not and if it is homogeneous or nonhomogeneous?
Q. I don't seem to get it but here are a few examples of equations I'm supposed to know wether they are linear or nonlinear and homogeneous or nonhomogeneous: 1) (dy)/(dx)=5y 2) (d^2 y)/(dx^2)+x=y 3) y + x sin x y' = y 4) y'' + 4y' - 3y = 2y^2 5) (d^3 y)/(dt^3) + t*(dy)/(dt) + t^2y = t^3 6) cos x * (dx)/(dt) + x sin t = 0 So yeah I'm seriously just looking at the whole page and thinking wtf?! And I'm trying to read it but it's all in english and it makes no sense to me (not my first language) so please if anyone could explain to me how I can know if it's linear or nonlinear and homgeneous or nonhomogenous it would be greatly appreciated :) Thank you

A. A linear differential equation can not have any products of derivitives of y or y itself. That means yy', and y^2 would produce nonlinearity for instance. In your case, 1, 2, 3, and 5 are linear. We have that 4 and 6 are non linear because of the y^2 in 4 and the x ' * cos x in 6 (x ' =dx/dt). Homogeneous and nonhomogeneous mean different things within the realm of differential equations depending on where you encounter them. Early on in a DE course, one studies the equation of the form y ' = f(x/y) which is said to be homogeneous. But more often, a linear differential equation is said to be homogenous if it does not contain any terms that are devoid of y or any of it's derivitives. FOr instance y'' + x^2 y' + 5y = 0 is homogenous (and… [cont.]

A. Stolen from Ask Dr. Math. You can decipher the meanings by looking at what the terms mean in English. The words go in pairs, and each means the opposite of the other. They are used to describe the solution of a system. The first pair is "consistent" versus "inconsistent." Now, keep in mind that you are applying these to a system of linear equations. We say that a point is a "solution" to the system when it makes BOTH equations true, right? This is to say that there exists a point (or set of points) that "work" in one equation and also "work" in the other one. So we say that this point is consistent from one equation to the next. On the other hand, if there are NO points that work in both, then we say that the equations are… [cont.]
