Write the system of equations corresponding to the augmented matrix. (Use x, y, and z as your variables, each representing the columns in turn. Write the equations for the system in the same order as they appear in the augmented matrix. Do not perform any row operations.) 0 3 2 13       1 −1 −2 -1   4 0 3 30

Write the following linear systems in augmented matrix form, wherethe variables are ordered using the regular alphabetical order. 7 − B + 4C − 3D = A + 2 − 3B − 5C5B + 9 = −1 + 2A + 6B + 6C + 2D

Write the following system of equations as an augmented matrix in echelon form.

You have space in your garden for 55 small flowering bulbs. Crocus bulbs cost $0.55 each and daffodil bulbs cost $0.95 each. Your budget allows you to spent $41.85 on bulbs. How many crocus bulbs and how many daffodil bulbs can you buy? Write a system of equations to represent the situation. Solve using matrices. Write the matrix and inverse equations.

Write the following system of equations as a single matrix equation. 5z -9x = 0 5y = -4+ 6z 8x +7y-10 = 0 Answer 72021 Hawkes Learning

Write the augmented matrix for the system of linear equations. -x - 7y + 8z = 7 24z = -35 y + 7z = -8x 7x 15 Step 1 Begin by rewriting the linear system and aligning the variables. -x - 7y + 8z = 24z = -35 7x - y + 7z = 15 -8x Use the coefficients and constant terms as the matrix entries and include zeros for the coefficients of the missing variables. ... ... ...
