Answer:
The second one
Step-by-step explanation:
Note that he can spend a MAXIMUM of $40 meaning that he can either spend less than or exactly 40 dollars. So if we are creating an inequality the inequality sign must face $40 and it can be equal to 40 therefore we know the inequality must start off with 40≥ or end with ≤40
The movie ticket cost 10$
The amount of money that can be spent on food can be represented by d
the amount of money that can be spent on food plus the cost of the ticket (10) must be equal to or less that 40
Therefore 10 + d ≤ 40
The answer is the second one

Answer:
4 parameters are necessary to specify all solutions and correspond to the number of free variables of the system.
Step-by-step explanation:
Remember that the number of free variables of a system is equal to m-rank(A) where m is the number of unknowns variables and A is the matrix of the system.
Since the system is consistent and the rank of the matrix is 3 then echelon form of the augmented matrix has two rows of zeros.
Then m-rank(A)=7-3=4.
