Inequalities are used to compare unequal values and expressions
The temperatures are given as:
<u>(a) Compare the temperatures</u>
Recall that the temperatures of the cities are:
-7 is less than -3.
So, the inequality that compares the temperatures of the cities is:
<u>(b) Explain the inequality in (a)</u>
As a general rule, lower values are placed to the left of a higher value on number lines
From the number line, we can see that -7 is to the left of -3.
Since -7 is placed at the left of -3, then it means that -7 is less than -3.
<u>(c) The warmer city</u>
The higher the temperature, the warmer the temperature.
This means that, city L is warmer than city M
