12 and 1 half minus 9 and 5 12’s

37/12

Step-by-step explanation: When you simplify both fractions the answer would be for 12 1/2: 25/2 and for 9 5/12: 113/12. You multiply 25/2 times 6 so both denominators are the same and you can subtract. Now 25/2 is 150/12 minus 113/ 12. You subtract 150 - 113 which is equal to 37. And you leave the denominator the way it is. So your answer would be 37/12 or 3 1/12.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
