08/06/2020 JESUS AND MARY SCHOOL AND COLLEGE MODULE-6 CLASS-8 (MATHS) CHAPTER NAME– INEQUATIONSNote: Please refer to the video prepared for this chapter.WORKSHEET-1If the replacement set is 0,1,2,3,4,5,6,7,8, find the solution set for each of the following inequations: i) x≤2 ii) x>0 iii) x≥5Represent the following inequations on number line: i) -1≤x≤4,x∈I ii) -2<x<2,x∈I iii) x<6,x∈N Solve the inequation 5x-1<2x+1,x∈W and represent the solution set graphically.What is the solution set of the inequation 2x-8>5+x, where the replacement set is a set of positive integers.Solve each inequality for x: i) 5x+3<28,x∈W ii) 4x-7<11x+14,x is a set of negative integersSolve 239x-15+4≤6+344-12x,x∈NNote- Please do this assignment in your copies. It will be checked when the school re-opens.SOLUTION TO WORKSHEET-1(Uploaded on 01/06/2020)Ans.1. i) 1728 ii) -216 iii) 9261 iv) -2700Ans.2. i) -125625 ii) 27125 iii) 8343 iv) -7291331 Ans.3. i) 0.027 ii) 0.512 iii) 0.000000001 iv) 121.67 Ans.4. i) 12 ii) 3375 iii) 18 iv) 9 Ans.5. i) 2.1 ii) 0.7 iii) 6.3 iv) 0.15 Ans.6. When you will find the prime factorization of the 9261, you will see that no prime factor is left unpaired. Therefore, it is a perfect cube and it is cube of 21. Ans.7. 53 or 123 Ans.8. 303121 Ans.9. It should be multiplied by 4 and cube root is 44.Ans.10. It should be divided by 4 and cube root is 15.*************** ................
