Solve the following system of linear equations by addition. Indicate whether the given system of linear equations has one solution, has no solution, or has an infinite number of solutions. If the system has one solution, find the solution.{−3x+y=28−6x+2y=56

Select ALL elements that are addressed during the revision stage of the writing process:

Solve the following system of equations by graphing. Then determine whether the system is consistent or inconsistent and whether the equations are dependent or independent. If the system is consistent, give the solution.{9x+9y=9−6x+3y=3

Consider the following system of equations.{2x+4y=−84x−4y=8−Determine if the point (3,−4) lies on both of the lines in the system of equations by substituting the ordered pair into both equations.

Solve the system of two linear inequalities graphically.{y≤x+2y>−5x−10Graph the solution set of the first linear inequality.

You will work on an estimated scope for this lab within conference room 421. The scope will include installing two poke-thru devices, including the conduit, fittings, cable, and terminations. This scope will exclude the conduit, fittings, wire, and terminations for the Division 26 power connections. Complete the estimate using the template below to find the total material price, total labor hours, and total project price based on an hourly rate of $35/hour, overhead calculated at 10% of the labor cost, and 10% profit. The dimensions are labeled on this sheet. Use these distances: A = 13′, B = 14′, C = 11′, and D = 18′. Complete the estimate.  

Solve the following system of equations by graphing. Then determine whether the system is consistent or inconsistent and whether the equations are dependent or independent. If the system is consistent, give the solution.{6x+3y=−18−6x+3y=−18

Solve the following system of linear equations by addition. Indicate whether the given system of linear equations has one solution, has no solution, or has an infinite number of solutions. If the system has one solution, find the solution.{10x+5y=−154x+2y=18−
