Answer:
Yes, it is a right triangle
Step-by-step explanation:
Answer:

Step-by-step explanation:
Product refers to multiplication, hence the 4x.
> what is the slope of the line?
The standard form of the linear equation is:
y = m x + b
where m is the slope, in this case the slope is m = 15
> What does the slope represent in the context of the
problem?
<span>The slope is the ratio of L over s. Therefore this means
that the slope represents the change in total length per change in the wear
welded onto the end</span>
For this case we have the following equation:

Where, by definition, we have the following variables:
d (x): the daily expense per truck (in dollars)
x: the daily mileage
Therefore, the domain of the function is given by:

Equivalently:
[0, ∞)
Answer:
The input for the function includes all positive real numbers
option d.
