Inequality x -3
Webif b is 1, then the answer is x < 3. but if b is −1, then we are solving −x < −3, and the answer is x > 3. The answer could be x < 3 or x > 3 and we can't choose because we don't know … But instead of saying "obviously x=6", use this neat step-by-step approach: Work … Turning English into Algebra.

Inequality x -3
Did you know?
WebExample: x ≤ 2 or x >3. On the number line it looks like this: And interval notation looks like this: (-∞, 2] U (3, +∞) We used a "U" to mean Union (the joining together of two sets). Note: be careful with inequalities like that one. Don't try to join it into one inequality: 2 ≥ x > 3 wrong! that doesn't make sense (you can't be less than 2 WebAn inequality is similar to an equation in that they both describe the relationship between two expressions. Below are some examples of inequalities: Examples. ½ ; ¾ 99.8 > 98.6; 2 + 3 ≠ 2 × 3; 3 × 2 ≤ 4 + 3; 11 ≥ 9; Properties of inequalities. Inequalities, like many other relations in math, are governed by certain properties.
WebThree-part inequalities. Three-part inequalities have two symbols in their expressions. Solving a three part inequality is the same as two part inequalities. As in: What you do to one side – You must do to the other. Except now you do it to all three sides. Example. Solve −4 ≤ 2x − 1 ≤ 5 - 4 ≤ 2 x - 1 ≤ 5. So try to get x x on its ... WebStrangely, this means that there are no solutions to the compound inequality because there's no value of x x x x that's both greater than negative one and less than negative one. ... To solve, subtract 2 all the way across, -8 ≤ 2x ≤ 6, then divide by 2 to get -4 ≤ x ≤ 3. Infinite amount of numbers between -4 and 3.

The points that divide the number line into regions are 0, 1, and 4. [None of these points are possible answers because the problem has > not >=.] We need to check one point from each of these regions: x < 0, 0 < x < 1, 1 < x < 4, x > 4. Region: x < 0: We can use any point, I will choose -5 and place this number into x (x -1) (x - 4 ...
WebThere are three possible outcomes for compound inequalities joined by the word and: 1. The solution could be all the values between two endpoints. 2. The solution could begin at a point on the number line and extend in one direction. 3. In cases where there is no overlap between the two inequalities, there is no solution to the compound inequality.

Reason: The graph has a closed filled in circle at -3, which means we include this value. So we'll have "or equal to" as part of the inequality sign. We'll also have "greater than" because we're shading to the right. Hence, we have "greater than or equal to".
