Solving equations and inequalities graphing

  • The graph of a compound inequality with an "or" represents the union of the graphs of the inequalities. A number is a solution to the compound inequality if the number is a solution to at least one of the inequalities. It is written as x < -1 or x > 2
Jul 27, 2011 · When solving linear inequalities, we use a lot of the same concepts that we use when solving linear equations. Basically, we still want to get the variable on one side and everything else on the other side by using inverse operations. The difference is, when a variable is set equal to one number, that number is the only solution.

Rewrite the equation in the form y = mx + c. From the equation m will be the gradient and c will be the y-intercept. 2x – 3y = 6 . y = x – 2 . The gradient is then and the y-intercept is – 2. If the inequality is „ or … then we draw a solid line. If the inequality is < or > then we draw a dotted line.

Step 1 We must solve for one unknown in one equation. We can choose either x or y in either the first or second equation. Step 2 Substitute the value of x into the other equation. In this case the equation is 2x + 3y = 1. Substituting (4 +... Step 3 Solve for the unknown. Remember, first remove ...

  • A Linear Inequality is like a Linear Equation (such as y = 2x+1)...... but it will have an Inequality like <, >, ≤, or ≥ instead of an =. How to Graph a Linear Inequality First, graph the "equals" line, then shade in the correct area.
  • Dec 21, 2020 · Linear inequalities with two variables have infinitely many ordered pair solutions, which can be graphed by shading in the appropriate half of a rectangular coordinate plane. To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality.

    To solve word problems we need to write a set of equations that represent the problem mathematically. The solution of the equations is then the solution to the problem. Problem Solving Strategy. Read the whole question. What are we asked to solve for? Assign a variable to the unknown quantity, for example, \(x\).

    Graph the inequality: 1) x < -5 2) x < 2 3) x > 3 4) x > -1. Solving and Graphing: Do all the same steps as solving equations to get the x by itself. When the x is by itself, then you can graph the solution set. 5) 3x – 4 < 2 6) ½ x – 7 > -8 7) 2(5x – 3) > 14 8) 8 – 3x < 17. THE ONE DIFFERENCE BETWEEN SOVING EQUATIONS AND INEQUALITIES

    The solutions for inequalities generally involve the same basic rules as equations. There is one exception, which we will soon discover. The first rule, however, is similar to that used in solving equations. If the same quantity is added to each side of an inequality, the results are unequal in the same order.
