Write the system first as a vector equation and then as a matrix equation. 8x₁ + x2 3x3 = 9 4x2 + 3x3 = 0 Write the system as a vector equation where the first equation of the system corresponds to the first row. Select the correct choice below and fill in any answer boxes to complete your choice.

Use an augmented matrix to find the solution of the system of equations. + 7y + 62 = -7 2y 2 = 19 2y + 22 = 1 X -5x 5x x = y = 2 =

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 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. ... ... ...
