Question

Which of the following inequalities has a solution x≥−3
3(x−1)≤4x

x≥x+32

x6≤x2−1

x+4≥x3

Answer 1

Answer: A

Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3
