Please check and correct if my answer is wrong, this is basic algebra . Thank you

7. Reflexive Property 8. Symmetric Property Explain: A value that Explain: If a valve gluses = to itself is easy to softer valve them that Zag valve Two Examples (NOT from class!) RT to the first Two Examples (NOT from class!) 6= 6 3=6 1 6-5 3 =3 9. Transitive Property 10. Use #1-9 to identify each property below. property Explain: If I vikee of A. ab' . 0 =0 Property B. (7 + 5) +1 =7+ (5+1) is seto shother and Reflexive c. 6 = 6 propell ther Ake Is = to distinctive property D. 7(x - 3) = 7x - 21 smother then, the first welle poperyy E. x + (-x) = 0 One Example (NOT from class!) Symmetric F. if y = 3, then 3 = y prones G. (a + b) + 0 = 0+ (a+ b) H. if x = -1, and -1 = z, then x = z Ident I. 4x .1 =4x 11. Is the set of integers closed under division? Explain why or why not. If it is not closed, give an example. The set of integers is not closed because sometimes the result is not always an integer 12. Is the set of real numbers closed under addition? Explain why or why not. If it is not closed, give an example. Rev/ numbers are closed because the result is slugs an integer
