Question

Identify the solution set of the inequality using the given replacement set

x ≤ -7; {-10, -7.2, -7, -6.9, 6.5, 9}

A. {-6.9, 6.5}

B. {-10, -7.2, -7}

C. {-10, -7.2}

D. {-7, -6.9, 6.5}

Answer 1

Option B is correct.

Solution set of the inequality is; { -10 , -7.2, -7}

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:
`x\leq -7` ;

`\{-10 , -7.2 , -7, -6.9 , 6.5 , 9\}`

The best choice for the solution of set of the inequality is: { -10 , -7.2, -7}
