The determinant of a 2 x 2 matrix can be calculated as:
Product of non-diagonal elements subtracted from product of diagonal elements.
The diagonal elements in given matrix are 12 and 2. The non-diagonal elements are -6 and 0.
So,
Determinant G = 12(2) - (-6)(0)
Determinant G = 24 - 0 = 24
So, option B gives the correct answer

Answer:
m ∈ R
Step-by-step explanation:
- 1,84 - 2,3m = - 2,3(m + 0,8)
- 1,84 - 2,3m = - 2,3m - 1,84
m ∈ R
Answer:
see explanation and attachment
Step-by-step explanation:
(1) y = -x + 2
so slope is -1 and y-intercept is (0,2)
(2) 2x - y = 7
y = 2x - 7
so slope is 2 and y-intercept is (0,-7)
