The linear equation is an equation that has one or two variables and those exponents are one. Linear inequation also has one variable whose exponent is one. Between two algebraic expressions, the = symbol is enclosed in a linear equation, linear inequality signs are enclosed in a linear inequation. The graph of inequalities is a dashed line but. Basic Practice. Let's solve some basic linear inequalities, then try a few more complicated ones. Just as with linear equations, our goal is.

Here are the steps for solving inequalities:. Step - 1: Write the inequality as an equation. Step - 2: Solve the equation for one or more values. Step - 3: Represent all the values on the number line. Step - 4: Also, represent all excluded values on the number line using open circles. Step - 5: Identify the intervals. Step - 6: Take a random number from each interval, substitute it in the. 19 Questions Show answers. Q. When you graph an inequality, you used a closed dot when you use which symbols? Q. When graphing an inequality, you use an open dot when you use which symbol? Q. Solve the inequality. Q. Pick the correct inequality. Inequalities are everywhere in real life. -- Your earnings need to be greater than or equal to your expenses. -- You are on an elevator. Somewhere it has a sign for the maximum occupancy for that elevator. So, the total weight of its passengers must be less than the maximum for the elevator to work properly.

x+5-5<7 x<7 *****NOTE- when multiplying or dividing by an NEGATIVE number you switch the inequality sign. eg. -9x > 12 -9x/-9 > 12/-9 x >-3 x <-3 Boundary Point: The number that will make the two sides of the linear inequality equal to each other. In other words, when solving the linear inequality the answer is the boundary point. Example:.

The distinction between solving linearinequalities and solving mathematical equation is the disparity symbol. Linearinequalities are solved in the same way that linear equations are. Step 1: Using the laws of inequality, simplify the inequality on both sides, LHS and RHS. Step 2: After obtaining the value, we have: Inequalities with stringent. LINEAR INEQUALITIES 121 or 6x – 8 ≥ x – 3 or 5x ≥ 5 or x ≥ 1 The graphical representation of solutions is given in Fig 6.2.
