How Do You Solve a Quadratic Equation with Two Solutions by Graphing? One of the many ways you can solve a quadratic equation is by graphing it and seeing where it crosses the x-axis. Follow along as this tutorial shows you how to graph a quadratic equation to find the solution. For questions 1 to 6, draw a graph for each inequality and give its interval notation. For questions 7 to 12, write the inequality represented on each number line and give its interval notation. For questions 13 to 38, draw a graph for each inequality and give its interval notation. Answer Key 4.1 Graph sketching software can be used in this section to ensure that graphs are accurate. Simultaneous equations can also be solved graphically. If the graphs of each linear equation are drawn, then the solution to the system of simultaneous equations is the coordinates of the point at which the two graphs intersect. For example:

Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Even though the simplex algorithm is not polynomial time, we mentioned in Chapter 7 that there is a different, polynomial algorithm for linear programming. Therefore, linear pro-gramming is efciently solvable both in practice and in theory.a) Solve the system consisting of the linear equations y = (1/2)x + 3 and y = 7 by graphing each equation. b) Solve the following system graphically: x – 3y = 2 and y = 6 – x. 17) Solve a linear system algebraically by the substitution method and the addition method. a) Solve the system by the substitution method.

Step 1: Graph every linear inequality in the system on the same xy axis. Remember the key steps when graphing a linear inequality: Isolate the “ y ” variable to the left of the inequality. If the symbols are > and ≥, we shade the area above the boundary line using dashed and solid lines, respectively. To graph the inequality y = -x + 6, we first graph the equation y = -x + 6 shown in Figure 7.13. Notice that (3, 3), (3, 2), (3, 1), (3, 0), and so on, associated with the points that are on or below the line, are all solutions of the inequality y = -x + 6, whereas (3,4), (3, 5), and (3,6), associated with points above the line are not solutions of the inequality.

To solve inequalities like [latex]a<x<b[/latex], use the addition and multiplication properties of inequality to solve the inequality for x. Whatever operation you perform on the middle portion of the inequality, you must also perform to each of the outside sections as well. Pay particular attention to division or multiplication by a negative. Yes we have two inequalities, because 3 2 = 9 AND (−3) 2 = 9 Add 4 to both sides of each inequality: 1 ≤ W ≤ 7 So the width must be between 1 m and 7 m (inclusive) and the length is 8−width .
