Python

python
import sympy as sp

A=sp.Matrix([[1,0,2],[0,-1,1],[-2,0,0]])
A.inv()

Matrix([
[  0,  0, -1/2],
[1/2, -1,  1/4],
[1/2,  0,  1/4]])

Python

python
from PIL import Image
import matplotlib.pyplot as plt

img = Image.open('/mnt/data/20250708_105156.jpg')
# Crop rough right column region
w, h = img.size
crop = img.crop((w*0.66, h*0.02, w*0.99, h*0.48))
plt.imshow(crop)
plt.axis('off')

(-0.5, 1319.5, 1379.5, -0.5)

Python

python
crop = img.crop((w*0.66, h*0.48, w*0.99, h*0.9))
plt.imshow(crop); plt.axis('off')

(-0.5, 1319.5, 1259.5, -0.5)

Clarifying matrix comparison

I'm comparing the B matrix from Q3 and Q9. They're not the same—Q3 has B as [2 1 3; 3 0 1; 3 -1 1], while Q9 has [2 1 3; 5 0 4; 3 -1 1]. Since B in Q9 is 3x3, I'll assume A and B are both 3x3. I need to figure out the missing entries for A. Next, I’ll check the chosen options for Q9, particularly focusing on the expression 5A - 2B from the image to confirm which answer matches.

Finalizing matrix calculation

Looking at the options for 5A - 2B, I can clearly compute the result. Starting with A = [1 0 2; 0 -1 1; 1 -2 0] and B = [2 1 3; 5 0 4; 3 -1 1], I calculate 5A, 2B, and subtract them. The result is [[1, -2, 4], [-10, -5, -3], [-1, -8, -2]], which shows that the correct answer is option E. Other options either don't match or provide incorrect results. So, the answer to Q9 is definitely E.
