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
Answer:
6 : 7
Step-by-step explanation:
Total books = 52
Fiction books = 24
Non-Fiction = Total - fiction
= 52 - 24
= 28
Therefore, the ratio from fiction to nonfiction would be
fiction : nonfiction
= 24 : 28
Simplify
= 12 : 14
= 6 : 7
You do nine divided by fifteen which =$0.6
