what is the Solving Systems Using Substitution quick check answers?
If one of the equation is in the form y = ....
or x = .... , or can easily be changed to one of those forms, I would use substitution
3x + 4y = 36
y = 2x+3
definitely use substitution
Which method would be the simplest way to solve the system? 7x +5y = 19 -7x-2y = -16 graphing substitution elimination or distributive
4x-3y=11,and 2x+5y=25, substitution method
1. I need help solving the system by substitution -x-y-z=-8 -4x+4y+5z=7 2x+2z=4
Solve the following system of linear inequalities by graphing. 3x – y < 2 x + y > 2
Xander says that the place value sections method, the expanded notation method, and the algebraic notation method of multiplying a one-digit number by a two-digit number are pretty much the same. Do you agree or disagree? Explain.
Explain the difference between solving a system of equations by the algebraic method and the graphical method. Someone also wants to know why there are different methods for solving the same problem-what would you tell him? Tiffany Oakes
Solve the system of linear equations using the substitution method. 3x + 3y = 0 -6x + 9y = -10
Calculate the monthly finance charge for the credit card transaction. Assume that it takes 10 days for a payment to be received and recorded, and that the month is 30 days long. $500 balance, 17%, $50 payment previous balance method, adjusted balance
Using the Disk Method or washer method (im not sure which one) Find The volume of y=x^3 , y=1 , x = 2 revolving around the X axis
Find the number of the solutions to each system. a. 4x-y+1=0 4x-y+3=0 b. 2x-y+4=0 4x-2y+8=0 Write a question that can be solved using a system of linear equations. Solve the following system of equations by graphing: y=x+3 and y=-2x-3
Solve each linear system by substitution method. x+2y=7 2x+4y=8 I'm getting stuck. Could some one explain the work out process and what the outcome means?
When solving a system of equations by the addition method, how do you know when the system has no solution?
How can you determine the best method of solving a system of equations?
Why does the first method for determining volume work only for a regularly shaped object? Will the second method for determining volume work for any object or just an irregularly shaped one? Why? Is one method of measurement more accurate than the other?
Is there a difference between solving a system of equations by the algebraic method and the graphical method? Why or why not?
Solve the system of linear equations, using the Gauss-Jordan elimination method. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions involving one parameter, enter the solution using t for the last variable. If the solution
For tax and accounting purposes businesses often have to depreciate equipment values over time. One method of depreciation is the straight-line method. Three years ago Hilde Construction purchased a bulldozer for $51,500. Using the straight-line method,
The ellipse x^2+3y^3=13, has two points when x+-1 . Find the slope of the ellipse at both these points. 2. Thoroughly explain the method you used to find the slope in part 1. What are the strengths and weaknesses of the method you used? 3. Explain whether
Use the Substitution method to solve the system of equations. y - 2x = -5 3y - x = 5 Solve one of the equations for x or y. Let's solve the first one for y: y - 2x = -5 y = 2x - 5 Now let's substitute 2x - 5 for y in the second equation to solve for x:
