Answer with Step-by-step explanation:
We are given that
A and B are matrix.
A.We know that for two square matrix A and B
Then, 
Therefore, it is true.
B. det A is the product of diagonal entries in A.
It is not true for all matrix.It is true for upper triangular matrix.
Hence, it is false.
C.

When is a factor of the characteristics polynomial of A then -5 is an eigenvalue of A not 5.
Hence, it is false.
D.An elementary row operation on A does not change the determinant.
It is true because when an elementary operation applied then the value of matrix A does not change.
Domain: all x values between the ends of a line on the x- axis
Range: all y values between the ends of a line on the y-axis
Answer:
the answer is 20
Step-by-step explanation:
180+180=360
80+70=150
180-150=20
Answer:
5. 100/b+24 6. 5m+13
Step-by-step explanation:
5. The quotient means Divide. The sum means Add. So / is z symbol for division. 100 divided by b plus 24.
6. More means to Add and the product means to multiply. So instead of putting m times 5, you would put 5m. First you would put 5m+ 13 b/c of the "than".
Hey there,
Answer: Tomatoes
If you multiply 10 x 0.69 (for onions) it would be 6.9
If you multiply 100 x 0.99 (for tomatoes) it would be 99
Lastly, if you multiply 100 x 0.69 (for lettuce) if would be 69
Which are the most? Tomatoes.
