55. To find the range of the given equation y = 2x + 1, we need to understand that range refers to the set of all possible output values of a function. In this case, as we have a linear equation, the range is all real numbers. Therefore, the answer is a. all real numbers.

67. To identify the property of the given equation -2 + (10 + 1) = (-2 + 10) + 1, we need to understand the different properties of addition. The equation displays the associative property of addition, which states that changing the grouping of the numbers being added does not change the sum. Therefore, the answer is d. Associative Property of Addition.

73. The question asks for the equation written in function notation. Function notation refers to expressing a function as f(x) = ... . Among the options, only option b. f(x) = 3x - 1 is written in function notation.

75. Similar to question 67, this question asks about the property demonstrated by the equation 7 + (4 + 4) = (7 + 4) + 4. By observing the equation, we can see that the grouping of the numbers being added is changing while the sum remains the same. This indicates the associative property of addition, and the answer is b. Associative Property of Addition.

99. The equation (ab)3 = a(b^3) is exhibiting the associative property of multiplication. The property states that changing the grouping of the numbers being multiplied does not change the product. Therefore, the answer is c. Associative Property of Multiplication.

So, the correct answers are:

55. a. all real numbers
67. d. Associative Property of Addition
73. b. f(x) = 3x - 1
75. b. Associative Property of Addition
99. c. Associative Property of Multiplication
