Writing Inequalities in Interval Notation. While writing the solution of an inequality in the interval notation, we have to keep the following things in mind. If the endpoint is included (i.e., in case of ≤ or ≥) use the closed brackets '[' or ']' If the endpoint is not included (i.e., in case of < or >), use the open brackets '(' or ')' Previous: 200,000,000th Website View Next: Surface Area Videos GCSE Revision CardsSkills for solving linear inequalities. representing and interpreting inequalities displayed on a number line; writing and interpreting set notation eg {x : x > 1} ∩ {x : x ≤ 7} is the same as 1 < x ≤ 7; writing and interpreting interval notation eg [-4, 6) is the same as -4 ≤ x < 6Answer: Interval notation: Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: . Solution: Both solution sets are graphed above the union, which is graphed below. This rule holds for all fractional multiplication and division. The rule is when you turn the fraction upside down the you also switch divide/multiply and it's the same thing. The same hold true when you convert the fractions into decimals. 1/2 = 0.5 and it's inverse 2/1 = 2. This means dividing by 0.5 is the same as multiplying by 2. inequality. Practice Questions.
