Question

which number line shows the solution of -3x + < 12 btw this is so that the correct answer can be shown when someone looks up this question i do this to questions my little bro looks up questions for his classes and there is no answer

Answer 1

B

Explanation:

First, solve the inequality:

-3x + 6 < 12

Subtract 6 from both sides:

⇒ -3x < 6

Divide both sides by 3:

⇒ -x < 2

Divide both sides by -1 (so reverse the sign)

⇒ x > -2

This means x is greater than -2

open circle: < or >

closed circle: ≤ or ≥

So we are looking for an open circle on -2 and shading above that
