B) Write the factored form of 3y - by. SOLUTION (a) 1a + 22x = ax + 2x (b) 3y - by = 13 - b2y Now try Exercise 37. Here are some properties of the additive inverse together with examples that help illustrate their meanings. Properties of the Additive Inverse Let u and v be real numbers, variables, or algebraic expressions. Property 1. 2. 3. 4. 5. 1 Real Numbers 7 Integer Exponents Exponential notation is used to shorten products of factors that repeat. For example, 1-321- 321- 321- 3) = 1-324 and 12x + 1212x + 12 = 12x + 122.

Objective Students will be able to convert between decimals and fractions, write inequalities, apply the basic properties of algebra, and work with exponents and scientific notation. The integers: 51, 2, 3, Á 6 50, 1, 2, 3, Á 6 5 Á , - 3, -2, -1, 0, 1, 2, 3, Á 6 The braces 5 6 are used to enclose the elements, or objects, of the set. The rational numbers are another important subset of the real numbers. A rational number is any number that can be written as a ratio a/b of two integers, where b Z 0.

1 suggests that the decimal form of 1/16 terminates and that of 55/27 repeats in blocks of 037. 0588235294. 0588235294117647. 17 Now try Exercise 3. The real numbers and the points of a line can be matched one-to-one to form a real number line. We start with a horizontal line and match the real number zero with a point O, the origin. 2. 2 The real number line. Every real number corresponds to one and only one point on the real number line, and every point on the real number line corresponds to one and only one real number.
