The freezing point of water is 0∘ C. Scientists use positive numbers to show temperatures above the freezing point of water and negative numbers to show temperatures below the freezing point of water. Snowy's Dessert Cart keeps the ice in their snow cones at a temperature of −15∘ C What does −15∘ C represent in this situation?

The -15°C temperature of the ice in their snow cones mean that the temperature of that ice is 15° below the freezing point of water.

Step-by-step explanation:

It is explained that Celsius scale was calibrated based on water. The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.

So, a temperature of -15°C simply means that the temperature is 15° lower than the freezing point of water.

Hope this Helps!!!

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
