Determine all positive number replacements (less than the modulus) for the question mark that make the statement true. 4 + ? = 3 (mod 6)

Q: Determine if the system has an identity element. If so,

Determine if the system has an identity element. If so, list the identity element. Explain how you determined your answer.

Q: Determine all positive number replacements (less than the modulus) for

Determine all positive number replacements (less than the modulus) for the question mark that make the statement true. 3 - ? = 7 (mod 9)

Q: The identity element is C. Determine the inverse, if it

The identity element is C. Determine the inverse, if it exists, of (a) A, (b) B, and (c) C.

Q: y = x + 3 y = -1 Solve

y = x + 3 y = -1 Solve the system of equations graphically. If the system does not have a single ordered pair as a solution, state whether the system is inconsistent or dependent.

Q: Determine all positive number replacements (less than the modulus) for
