D. Is the statement "Two fundamental questions about a linear system involve existence and uniqueness" true or false? Explain.

True

Step-by-step explanation:

Because two fundamental questions address whether the solution exists and whether there is only one solution.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

the reason why your question keeps getting deleted because this is not a school related question : )
