2 answers:
Answer:
-21
Step-by-step explanation:
I assume this is a 2 by 2 matrix.
determinant = -5 * 4 - 1 * 1 = -20 - 1 = -21
Answer:
Option A.
Step-by-step explanation:
If a matrix is defined as
then its determinant is
Let the given matrix is
We need to find the determinant for the given matrix.
Using the above formula we get
The determinant of given matrix is -21. Therefore, the correct option is A.

D because you know it can’t be a or b and the bigger number goes first
7 7/8= 63/8
3 1/4= 13/4
63/8 -13/4 we bring to the same denominator
(63-26)/8= 37/8
Answer:
27
Good one! Didn't trip me up tho
Answer:
the number would be 11
Step-by-step explanation:
8 · x - 3 = 64
________ _ (divide both sides by 8)
8 8
x - 3 = 8
+ 3 + 3
x = 11
(check:
11 - 3 = 8
8 x 8 = 64 )
X + 2 < -4
x < -4 -2
•x < -6
