(PA) Inequalities Warmup

Labelling

Ok....one last time....drag the solutions shown to the matching graph.

Drag labels to their correct position on the image

Labelling

You see the variable "x" ... place a "<" or ">" next to the x, then the number that finishes the solution.

Multiple Choice

What is the solution to this inequality. Hint...check out where the variables are inside the solutions.

• $$-7\ \ge\ x$$

  which is the same as $$x\ \le\ -7$$ $$-7\ \le\ x$$

• $$-7\ \le\ x$$

  which is the same as

  $$x\ \ge\ -7$$

• $$7\ \ge\ x$$

  which is the same as

  $$x\ \le\ 7$$

• $$7\ \le\ x$$

  which is the same as $$x\ \ge\ 7$$
