Question

If replacement set is (1,3,4,5,6,7,8,9), find the solution set in each of the following-
(I) x≤6
(ii) x>4
(iii) x<1
(iv) x≥9​

Answer 1

Replacement set= −5,−3,−1,0,1,3,4

(i) Solution set of x<−2=−5,−3

(ii) Solution set of x>1=3,4

(iii) Solution set of x≥−1=−1,0,1,3,4

(iv) Solution set of −5<x<3=−3,1,0,1

(v) Solution set of −3≤x<4=−3,−1,0,1,3

(vi) Solution set of 0≤x<7=0,1,3,4
