determinant method

>A system of linear equations is said to be consistent if it has at least are solution, otherwise it is inconsistent. Let A be asquare matrix of order n. Following are the steps to find the inverse of a matrix. Step 1: Find the value of the determinants A. That is, find |A| Step 2: If |A|..

The graphical method is applicable to solve the LPP involving two decision variables x 1 , and x 2 , we usually take these decision variables as x, y instead of x 1 , x 2 . To solve an LPP , the graphical method includes two major steps. a) The determination..

In order to determine the molecular mass of unknown non volatile compound, a known mass (say w g) of the compound is dissolved to prepare a known volume (say v liters) of solution. The osmotic pressure of the solution is determined and the molar mass is calculated as follows: wh..

Using the substitution method, find the number of solutions the given linear system has. 6 x + 2 y = -7 -3 x - y = 3 => Infinitely many solutions or No solution or Exactly one solution or Cannot be determined..

State whether the system is consistent and independent, consistent and dependent or inconsistent using the elimination method. 9 x + y = 10 y - 9 z = 82 10 x + 10 z = - 80 => Inconsistent or Cannot be determined or Consistent and dependent or Consistent and independent..

State whether the system is consistent and independent, consistent and dependent or inconsistent using Elimination method. 6 x - 7 y + z = 14 x + y - z = - 1 7 x = 6 y + 13 => Consistent and dependent or Inconsistent or Consistent and independent or Cannot be determined..

State whether the system is consistent and independent, consistent and dependent or inconsistent using the elimination method. x - 11 y - 120 z = - 122 11 x + y = 100 z 10 x + 30 z = 133 - 13 y => Cannot be determined or Inconsistent or Consistent and dependent or Consistent and..

State whether the system is consistent and independent, consistent and dependent, or inconsistent: using Elimination method. x + y + z = 5 3 x + 6 y - 3 z = 4 x + 10 y - 17 z = 6 => Consistent and dependent or Cannot be determined or Inconsistent or Consistent and independent..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using Elimination method. x 3 + y 2 + z = 3 2 x 3 - y - z 2 = 5 y + 5 z 4 = 1 => Inconsistent or Consistent and dependent or Cannot be determined or Consistent and independent..

The amount of phosphorus present in any organic compound is determined by Carius method..
