Which of the following is an example of a linear system of equations? O 5x2 +6y = 13 6x - 12y = 14 5x + 6y 13 6x 12y = 14 O 5x + 6y = 13 6x2 12y 14 O 5x + 6y= 13 6x- 12y 14

Show all work to verify if the given point is a solution to the system of equations. (3y² + 3x² = 6 4y² — 16x² + 12 = 0 Point: (-1,-1)

Determine the value(s) of k such that the system of linear equations has the indicated number of solutions. (Enter your answers as a comma-separated list.) No solution x + ky = 5 kx + y = 2 k=

The linear system is not in echelon form. Correct Letter(s): 6x1 Begin by choosing which of the following statements are correct. If there is more than one reason why the system is not in echelon form, type the letters as a comma separated list. Now write the system in echelon form. Equation 1: Equation 2: Equation 3: 3x3 = -6 3x3 X2 + 7x2 + 3x3 A. The system is not in echelon form because a variable is the leading variable of two or more equations. - B. The system is not in echelon form because the system is not organized in a descending "stair step" pattern so that the index of the leading variables increases from the top to bottom. stem is not in echelon form because not every equation has a leading variable. (x1, x2, x3): = = 0 12 Finally, solve the system. Use x1, x2, and x3 to enter the variables x₁, x2, and x3. If necessary, use s1, s2, etc. to enter the free variables $1, 82, etc. -(000)
