Solve the following inequation m+3>5 -3 -3 0 1 m>2 The inequation can be graphed on number line. -5 -4 -3 -2 -1 2 3 4 5 Draw arrow in the direction of the inequality sign. Use an open circle as the inequation has no equal sign. 2
Solve the following inequation b - 2 > -5 +2 -5 -4 -3 +2 b > -3 Graph on number line. -2 -1 0 1 2 3 4 5 Draw arrow in the direction of the inequality sign. Use an open circle 3
Solve the following inequation 4 w ≤ 12 ÷ 4 -5 -4 -3 w≤ 3 Graph on number line. -2 -1 0 1 2 3 4 5 Draw arrow in the direction of the inequality sign. Use a CLOSED circle Because of equals sign. 4
Solve the following inequation h ÷ 2 ≥ -1 x 2 -5 -4 -3 h ≥ -2 Graph on number line. -2 -1 0 1 2 3 4 5 Draw arrow in the direction of the inequality sign. Use an CLOSED circle Because of equals sign. 5
