Question

35. WEATHER Kenya saw this graph in the local weather forecast. It shows the predicted temperature range for the following day. Write an inequality to represent the number line.​

Answer 1

The inequality which represents the number line is : 54 >= x <= 68. The correct option is A.

From the graph,

• The leftmost point marked on the graph is : 54
• The righmost point marked on the graph is : 68

Both points have a shaded circle on top, indicating that a less than equal (<= or >=).

The leftmost point starts on 54 and extends to the right , indicating (>=)

• x >= 54

The rightmost point starts on 68 and extends to the left , indicating (<=)

• x <= 68

Combining the inequality:

• 54 <= x <= 68

Hence, the inequality which represents the number line is : 54 <= x <= 68
