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
If you do 18/24 you’ll get the answer of 0.75. Which is equal to 75%

I am pretty sure this is how you do it! Hope this helps!
Answer:
40
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
10/5 = 2
We multiply the last term given by the common ratio to get the next term
20* 2= 40
