Why does it flip?
Show answer
Because multiplying by a negative reverses order on the number line: 2<32 < 3 is true, but −2<−3-2 < -3 is false; the correct statement is −2>−3-2 > -3.
What is q1?
Show answer
Solve −5x≤20-5x \le 20. [2 points]
What is q2?
Show answer
Solve 3x+2<113x + 2 < 11. [1 point]
What is wrong circle type?
Show answer
Use an open circle for << or >> and a closed circle for ≤\le or ≥\ge. Mixing these loses the point on graphing items.
