Question

Which of the following values are solutions to the inequality 2 > -1 – 2x?I.3II. – 5III. – 6NoneI onlySubmit AnswerII onlyIII onlyI and III and IIIII and IIII, II and III

Answer 1

we have

2 > -1-2x

solve for x

2+1 > -2x

3 > -2x

divide by -2 both sides

REmember that

when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

- 3/2 < x

-1.5 < x

Rewrite

x > -1.5

therefore

Option I is a solution

Option II is not a solution

Option III is not a solution

answer is

I only
