WebLearn about inequalities using our free math solver with step-by-step solutions. WebYou only need to switch the inequality sign when you multiply or divide both sides of the inequality by a NEGATIVE number. I find this sometimes makes more sense if we take all of the variables away and just look at numbers. For example, 3 < 4, right? Well what happens if I multiply both sides by -2, and I DON'T remember to switch the signs?

WebWhen solving inequalities, like, say, this one: -2x+5<25 You would cancel out the +5 with -5 and subtract 25 by 5, so you're left with this: -2x<20. But now, since you're dividing by -2 (remember that multiplying or dividing by a negative number will reverse the sign) it will no longer be less than, it will be greater than: -2x/-2>20/-2 x>-10. WebThe shading is determined by the inequality. If the inequality is less than: y < mx+b, you shade below the line. If the shading is greater than: y > mx+b, you shade above the line. If you want to confirm that you have shaded the correct side, pick a point from the side where you shaded. Then, test that ordered pair in the inequality.

WebSep 5, 2024 · Use an algebraic equation to find the ages of Amanda and her dad. One way to solve this problem is to use trial and error—you can pick some numbers for Amanda’s age, calculate her father’s age (which is twice Amanda’s age), and then combine them to see if they work in the equation. nauticstar 195WebFeb 20, 2011 · That's the whole point in multiplying by -1, that we'll get positive numbers instead of negative numbers, and the equation is still valid because we'll be doing it to both sides. We get 3x = 5 Now, we can just divide both sides by 3. We get X = 5/3 Thus, we've arrived at the same answer. nautic star 1900xs offshore owners manual

"WebNov 16, 2024 · These solutions must be written as two inequalities. Here is the general formula for these. If p ≥ b, b > 0 then p ≤ −b or p ≥ b If p > b, b >0 then p <−b or p > b If p ≥ b, b > 0 then p ≤ − b or p ≥ b If p > b, b > 0 then p < − b or p > b Again, we will require that b b be a positive number here. Let’s work a couple of examples. " - How to solve inequalities math antics
