6. Does the following system have a unique solution? Why? (3x - 2y - 5
{-x+2y = 4
Yes, because the determinant of the coefficient matrix is 0.
No, because the determinant of the coefficient matrix is 0.
Yes, because the determinant of the coefficient matrix is 4.
No, because the determinant of the coefficient matrix is 4.

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
