For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
To help you , divide 1/4 and that will give you 0.25. 0.25 is greater than 0.15 so put the sign eating the 1/4. (Btw this is question 4)
The answer is D, (x + 1) (x + 2) (x - 3)
