If a < b and c < 0, then ac > bc. The Rectangular Coordinate System Just as you can represent real numbers by points on the real number line, you can represent ordered pairs of real numbers by points in a plane. In Exercises 5–10, solve the equation. Technology: Tip You cannot represent a circle or a parabola as a single function of x. Is x a monomial. When you construct an equation, be sure to check that both sides of the equation represent the same unit of measure. Place an asterisk (*) in the margin next to an especially important sentence or term. Vertical Pattern: Add terms. Tractrix A person walking along a dock (the y-axis) drags a boat by a 10-foot rope (see figure).

To find the demand that corresponds to a price of $6. X 3y 1 is the equation of the upper ray because the slope of the line is negative. Joint Variation The model used in Example 8 involved both direct and inverse variation, and the word "and" was used to couple the two types of variation together. 43 2x ≤ 32x 6 x ≤ 3 98.

The only other common types of functions are trigonometric functions, which you will study if you go on to take a course in trigonometry or precalculus. The return distance from the apartment complex to the pizza shop is 16 miles. Another way of saying this is "invert the divisor and multiply. Vertices: 0, ± 1; Co-vertices: ± 15, 0. The given information about the population can be described by the following table. B. y 2zz 3y Remind students to follow the order of operations when evaluating expressions. What does this tell you about the inverse properties of exponents and logarithms? In the following models for the data, t 5 corresponds to the year 2005.

Rules of Exponents Let m and n be positive integers, and let a and b represent real numbers, variables, or algebraic expressions. Also note that the highest point on the y-axis is now 30 because you changed the maximum value of y to 30. It can be agonizing to discover that you lost points on a test only because you failed to follow the directions. 26. f x. gx x 1 (a) f gx. Describe the pattern for the y-coordinates. 7x2 3 5x 5 ± 109 14. In Exercises 11 and 12, sketch the line through the point with each indicated slope on the same set of coordinate axes. Check the solution in each equation in the original system, as follows. So, the focus is 818, 1. How many miles must you drive in a week so that the rental fee for Company B is more than that for Company A? Next, draw the asymptotes of the hyperbola through the corners of the central rectangle and plot the vertices. Sketch graphs of equations using the point-plotting method.

Describe the three conditions that characterize a simplified radical expression. 2 Solve linear equations involving fractions. If your calculator performs the established order of operations, it will display 18. Each ounce of food X contains 20 units of calcium and each ounce of food Y contains 10 units of calcium. Set of natural numbers.

1 In Exercises 125–132, evaluate with a calculator. Study Tip For a hyperbola, note that a and b are not determined by size as with an ellipse, where a is always greater than b. Leading Coefficient 1. 2x2 3 5x1 3 3 0. x 2 5 x 6 0 2 2x1 3 5x1 3 3 0. In Exercises 23– 42, identify the center and radius of the circle and sketch the circle. 3 6 2 54. x 52 92 2 3 7 56. z 25 10 10. For instance, the verbal form of the Product Property lnuv ln u ln v is: The log of a product is the sum of the logs of the factors. Of the two possible solutions, choose the positive value of w and conclude that the picture is w 12 inches wide and w 6 12 6 18 inches tall. For instance, the numbers 2, 0, 1, 12, and 2 are real numbers (but they are not imaginary numbers), and the numbers 3i, 2 4i, and 1 i are imaginary numbers (but they are not real numbers). 2x y 2 You might point out that the solution obtained by substitution is the same solution that would be found by graphing. Graphing Equations In Exercises 9–12, use a graphing calculator to graph the function.
