Answer:
-2 is your answer
Step-by-step explanation:
First, you get 2/3 and distribute it into the parentheses that gives you
4-6x=16
now you subtract 4 on both sides leaving you with
-6/-6 which cancels out you have
12/-6 whigh is -2 and that is your answer
Answer:
you'd get the expression 6.37+7.8k
Answer:
I.
A is a 4 x 5 matrix => A: U -> V, dim U = 5, dim V = 4
Null space is exactly two dimensional plane
dim null (A) = 2
II.
Rank A = dim U - dim Null A = 5 - 2 = 3
III.
Number of linearly Independent columns of A is the rank of A = 3
IV.
Yes, The system Ax = b has no solution sometimes as range of A \neq V
V.
Yes,Sometimes Ax = b has a unique solution
VI.
Yes, sometimes Ax = b has infinitely many solutions
