Answer:
Option B is correct.
Solution set of the inequality is; { -10 , -7.2, -7}
Step-by-step explanation:
Replacement set states that the set from which the values of the variable which involved in the inequation are chosen.
Solution Set states that a solution to an inequation is a number chosen from the replacement set which satisfy the given inequation.Then, the set of all solutions of an inequation is known as solution set of the inequation.
Given the statement:
Relacement set: [tex]x\leq -7[/tex] ;
[tex]\{-10 , -7.2 , -7, -6.9 , 6.5 , 9\}[/tex]
The best choice for the solution of set of the inequality is: { -10 , -7.2, -7}
