Question

Step 3:Solve and denote the solution in interval notation.
Step 3:Solve and denote the solution in interval notation. 4x + 1 2(x + 2)

Explanation / Answer

4x + 1 >= 2(x+2) Distribute the 2: 4x + 1 >= 2x + 4 Subtract 2x from both sides: 2x + 1 >= 4 Subtract 1 from both sides: 2x >= 3 Divide both sides by 2: x >= (2/3) ***If we had divided (or multiplied) by a negative number you have to switch the signs. ie. >= would have become = (2/3) our interval is [(2/3), infinity) Since x could be equal to (2/3) we use the hard bracket on that side, and infinity always has a parenthesis.
