Inequalities On A Number Line Gcse Steps Examples Worksheet Example 1: single values. represent x>3 x> 3 on a number line. identify the value that needs to be on the number line. in this example it is 3 3. 2 decide if this needs to be indicated with an open circle or a closed circle. as the symbol is > then it will be an open circle. Inequalities gcse questions. 1. (a) write down the inequality represented on this numbers line. (b) list the integer values satisfied by the inequality in part a). (3 marks) show answer. 2. (a) solve this inequality 5x–1 <195x–1 <19. (b) represent your solution to part a) on the number line below.
Inequalities On A Number Line Gcse Steps Examples Worksheet Worksheets Library In effect these inequalities are showing what values of x are not allowed. step 1) identify the values on the number line. the value 1 ½ needs to be a closed circle as the symbol is ≤. the value ½ needs to be a closed circle as the symbol is ≥. step 2) draw line from each of the circles in the right direction. Question 2: display the inequality x \le 4 on a number line. [1 mark] question 3: display the inequalities y>3 and y< 2 on the same number line. [2 marks] question 4: display the inequality 1\leq x \leq8 on a number line. [2 marks] question 5: a school offers the option of gcse drama for year 10 and 11 students. Example 4: solving linear inequalities with unknowns on both sides. solve. 5x − 6> 2x 155x− 6> 2x 15. rearrange the inequality so that all the unknowns are on one side of the inequality sign. show step. in this case you need to subtract ‘2x’‘2x’ from both sides. rearrange the inequality so that ‘x’‘x’s are on one side of. Next: solving inequalities textbook exercise gcse revision cards. 5 a day workbooks.

Putting the inequalities together: 𝟓𝟓≤𝟑𝟑< 𝟕𝟕. step 3: draw a number line to illustrate the inequality region. the number line has a filled circle at 5 since 𝑥𝑥 can take value 5. there is a non filled circle at 7 since 𝑥𝑥 cannot take the value 7. step 4: list the set of integers which satisfy the number line. 1.!match each inequality to the correct description. (2) 2.!represent the inequality x > 2 on this number line. (1) 3.!represent the inequality x ≤ 4 on this number line.
