Question

Solve. Write your answer in interval notation.

Hint: First solve each inequality for x, and graph each inequality on a number line.

2x+4<10 or 3x+4≥37

Answer 1

Answer: x < 3 or x ≥ 11

(-∞, 3) or [11, ∞)

Explanation:

subtract 4 from each side

2x < 6 . or . 3x ≥ 33

x < 3 or x ≥ 11

make sure you have an OPEN DOT at 3 pointing to negative infinity and a CLOSED DOT at 11 pointing to positive infinity.
