Answer:
(a) a=6 and b≠
(b)a≠6
(c) a=6 and b=
Step-by-step explanation:
writing equation in agumented matrix form
now
now
a) now for inconsistent
rank of augamented matrix ≠ rank of matrix
for that a=6 and b≠
b) for consistent w/ a unique solution
rank of augamented matrix = rank of matrix
a≠6
c) consistent w/ infinitely-many sol'ns
rank of augamented matrix = rank of matrix < no. of variable
for that condition
a=6 and b=[tex]\frac{11}{4}
then rank become 3 which is less than variable which is 4.

just is loll
Given:
The expression is:
To find:
The value of the given expression.
Solution:
We have,
On simplification, we get
Therefore, the value of the given expression is 11025.
Answer:
No, it is incorrect. The line should be solid, not dotted, because it's a ≤ sign, not a < sign.
The terms of an expression 4x² – 3xy are:
(a) 4x and -3xy (b) 4x² and 3xy
(c) 4x² and -xy
(d) x
Answer:
(b) 4x² and 3xy
Step-by-step explanation:
The terms of an expression 4x² – 3xy are:
The terms are the factors of the expression, which are 4x² and -3xy. The signal is not counted as a term. So the correct answer is given by option b.
