How to solve inequalities with polynomials

WebIf you have a number outside of the absolute value sticks, get it to the other side of the inequality first then proceed. So in your example: 5 4 - 3x >= 30 divide each side by 5 to get 4 - 3x >= 6 then finish the problem as you normally would. If the problem had been: 4 - 3x + 5 >= 30 subtract the 5 from each side to get 4 - 3x >= 25 WebOct 6, 2024 · We begin by examining the solutions to the following inequality: x ≤ 3 The absolute value of a number represents the distance from the origin. Therefore, this equation describes all numbers whose distance from zero is less than or equal to 3. We can graph this solution set by shading all such numbers. Figure 2.6.6
