How do solve system equations with the different methods?
Q. I am baffled on how to figure this problem out. I am trying to solve the system of equation by graphing then classify system. The problem is: 5x-y=14 5x+6y=-14 Can someone help me in the detailed steps on how to solve this. I am trying to learn this but not grasping.

A. two equations two unknowns 5x - y = 14 5x = 14 + y replace in second equation and solve (14 + y) + 6y = -14 (subtract 14 from each side) y + 6y = -28 7y = -28 (divide both sides by 7) y = -4 put y back into one of the eq and solve for x 5x - (-4) = 14 5x + 4 = 14 5x = 10 x =2 IronButt Out

How do you solve percentages in your head?
Q. Whats the method for solving percentages in your head? How do you solve them in a calculator?
Asked by Derica H - Sat Jan 17 21:28:21 2009 - - 3 Answers - 0 Comments
A. percents in your head are based off of the simplest percents you can find. If we take our number and divide by 10, that gives us 10%, if we divide by 100 that gives up 1%, from there it depends on what we want to find, i usually use this to find a tip on a bill. if the bill is $60 and i'm looking for a 15% tip, i divide by 10 which is 6, so 6 is 10% of 60, then i can take half of 6 which is half of 10% which is 5%. so 3 is 5% of 60, if i add these together i have 9 or 15% of 60. Solving for percents on a calculator is just multiplying and dividing by 100. 60% of 40 is 60x40 / 100 = 24

A. Carla, Your screen needs to fit your slurry. Now I'm not sure how big of a piece your after but 3/4 to fine is what i'm thinking here if that's the case a 1" screen should be ok ..If your screen is inclined for overburden roll-off then the size needs to be one size larger maybe a 1.250..If your screen is passing all the crushed stone then your under vibrating and overloading the screen. You can slow the flow with baffles or just add a motor speed control to the conveyor feeding ..If your adding with a loader just dump slower...If your vibrating screen is hard to start you need to look for clumping in the grid. If the material is dry and your screen is hard to start the only thing you can do is change to a more excited screen vibratory… [cont.]

How do you solve for x and simplify equations on a graphing calculator ?

A. It has a equation solver. Press the MATH button and scroll down to solver. You have to have the equation equal to zero before you to it in. So if the equation was 4x - 3 = 17. You would have to put in the equation as 4x -20 = 0.

A. Let x = the length of the patio x - 12 = the width of the patio Now we're stuck. You need one more piece of information in order to come up with numerical answers for the dimensions of the patio. If you only have the information you posted in the question, your answer is what I posted above (x and x-12). Check to see if you left out the area of the patio or its perimeter.

Asked by Edd B - Thu Jan 8 22:43:44 2009 - - 1 Answers - 0 Comments
A. Just as there is a procedure for quadratics, there is also a procedure for cubics: but if you haven't studied this, it isn't likely that that's what is expected. If you are looking for a numerical solution (as opposed to a symbolic one), you can note that: F(1) > 0 and F(0) < 0 so there must be at least one positive root (i.e. between 0 and 1) so you can use a number of numerical methods to find it. (Bisection, Newton's method, secant method, etc.) Once you have the root r, you can divide F(x) = 9x^3-7x^2+10x-4 by (x - r) to get a quadratic. Then you can apply the formula that I'm sure you have been taught to get the roots of the quadratic. BTW, you can test your answers here:

The system of equations I am currently attemping to solve is as follows: 3x - 4y = 21 4x + 2y = 6 I know how to solve this equation using substition and graphing but am unable to do it with linear combinations. Thanks! Any assistance is greatly appreciated!

A. Any linear equations that can be put into the form a0x+b0y+c0z+...p0q=k0 a1x+b1y+c1z+...p1q=k1 a2x+b2y+c2z+...p2q=k2 * * anx+bnx+cnz+...pnq=kn are called simultaneous' equations if they have (or we think that they may have) a common solution point. Equations in this form can *always* be 'reduced' to the form (called 'upper triangular') 0x+ss0y+ 0x+... 0p=ue0 0+ ss1y+ 1x+... 1p=ue0 0+ 0+ 3x+... 3p=ue0 * * 0+ 0+ 0+... np=uen by adding and/or subtracting multiples of various rows to other rows. When complete p=uen/ n and the rest of the variables may be found by continued back substitution. This is called the 'Gauss-Jordan Elimination' method. If there is a problem and the family of equations 8cannot8 be put in upper… [cont.]

What are home ways to solve a itch that keeps reaccuring?
Q. My boyfriend's mother, step-dad and brother have a rash that they have had for a while. It isn't going away, and they don't have the money to go to the Doctor.

A. Try telling them to use some good lotion to keep their skin moisturized daily. It might just be cause its very dry. I have very sensitive skin. Palmer's Cocoa butter help me out. They can also use some Cortizone10..its 1% Hydrocortisone Anti-Itch Creme with Aloe. You can find at places like rite-aid, walmart, pharmacy, etc. Hope that helps.. :)

How do I learn to solve a Rubik's Cube by using logic and not by memorizing algorithms?
Q. Also, how do people learn to solve Rubik's cubes in less than, for example, 20 seconds? I want to learn how to do this because just repeating the same algorithm sequence is getting really boring.

A. It is very difficult to do without algorithms. You could learn a method such as the Petrus method which uses very few algorithms. Unfortunately, you probably won't get to world champion speeds with it. Almost all speedcubers use the Fridrich F2L method which involves learning quite a lot of algorithms. I'm assuming you use the 7 step beginner method which involves doing R', D', R, D a lot. Try learning a new method for the top layer - you will only have to learn a few algorithms and you won't get bored of doing the same one over and over again.
