Inequality Variable on Both Sides

Where is the first mistake?

• Subtracting 3 on both sides

• Distributing the 9

• Subtracting 9x on both sides

• Inequality error

Solve.

- 8 > 56 - 8b

• b > 8

Solve for k in the following inequality and choose the best answer to match the graph: 2k - 9 ≤ -19

• The graph would have a closed circle shaded left at -5.

• The graph would have a closed circle shaded left of 5.

• The graph would have an open circle shaded left of -5.

• The graph would have an open circle shaded left of 5.
