Answer:

-13.9 represents the slope

It is the number of units of the product left in stock per week

The negative value shows it decreases per week

Step-by-step explanation:

Here, we want to state what the value -13.9 represents

Generally, the equation of a straight line can be represented by the equation

y = mx + c

where m is the slope

In this case, -13.9 represents the slope of the model

The slope is calculated by dividing a change in y by a change in x

With respect to the question, the slope here represents number of units of the product left in stock per week

Answer:

Radical expressions must be simplified before adding or subtracting so that you are combining “like terms”. In the same way that 2x2 and 3x cannot be combined because they are not like terms, terms involving radicals cannot be combined unless the value under the radical is the same for both terms.
