Given the system of equations, what is the value of the system determinant? x + y = 8 x - y = 10 0 -1 -2

Each X and Y in the equations don't have a number in front of them so they are all considered 1.

D = 1*(-1) - 1*(-1) = -1 -1 = -2

The answer is -2

-2

Step-by-step explanation:

We need to set up the matrix to find the determinant

a  b

c  d

To find the determinant we take ad - bc

x + y = 8

x - y = 10

Take the coefficients of the x and y terms

1  1

1 -1

1 (-1) - (1) *1

-1 - 1

-2

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
