33. x>- 34 x + x> x 35. x' x 36 x + y = lx + Iy| 37. -x< x (x+ 1)(x-1) 38. = x + 1 Hint: Division by zero is (x - 1) undefined. 39. If the sum of two natural numbers is even, then the product of the two natural numbers is even. 40. If the product of two natural numbers is even, then both of the numbers are even numbers. 41. Pick any three-digit counting number. Reverse the digits of the original number. The difference of these two numbers has a tens digit of 9. 42. If a counting number with two or more digits remains the same with its digits reversed, then the counting number is a multiple of 11. 43. Use deductive reasoning to show that the following procedure always produces a number that is equal to the original number. Procedure: Pick a number. Multiply the number by 6 and add 8. Divide the sum by 2, subtract twice the originai number, and subtract 4. 44. Use deductive reasoning to show that the following procedure always produces the number 5. Procedure: Pick a number. Add 4 to the number and multiply the sum by 3. Subtract 7 and then decrease this difference by the triple of the original number. 45. Stocks Each of four siblings (Anita, Tony, Maria, and Jose) is given $5000 to invest in the stock mar- ket. Each chooses a different stock.
