The symbol X comes from the Greek alphabet (X=chi), circa 9th century BCE. The Etruscan alphabet is a direct descendant of the Greek alphabet and the Roman alphabet descends from the Etruscan. The Roman numerals themselves are thought to derive from an Etruscan tally stick method of counting.

There is no exact symbol. What you can do is subtract the symbol of 10 (X) from the symbol of 50 (L) by placing the smaller number in front of the larger as such, XL.
XHM is not a Roman numeral. There is no Roman numeral with the symbol H and although there are numerals with the symbols X and M, X would never be placed before M in a numeral.
To write the number 9 in Roman numerals, you would use the symbol 'IX'. This is made by combining the Roman numeral for 1, 'I', and the Roman numeral for 10, 'X', subtracting 1 from 10.
XLIX = 49
In Roman numerals, "XXXIX" represents the number 39. This is derived by adding the values of each Roman numeral symbol: "X" (10) + "X" (10) + "X" (10) + "IX" (9). Therefore, XXXIX equals 39 in our modern decimal system.
