Without graphing the equations, decide whether the system has one solution, no solution, or infinitely many solutions. 4y = x - 9
6x - 8y = 18

How many solutions does the system have?

A. One solution
B. Infinitely many solutions
C. No solution

To diagonalize an nxn matrix a means to find an invertible matrix p and a diagonal matrix d such that a pdp d p ap or [1 3 dh epap 3 let a=-3 -5 -3 3 3 1 step 1: find the eigenvalues of matrix a "2's" step 2: find the corresponding eigenvectors of a step 3: createp from eigenvectors in step 2 step 4 create d with matching eigenvalues.
