Im pretty sure all u need to do is multiply and you got your answer
There are no real solutions to the problem.
The discriminant is -96 when the discriminant is a negative number it has no real solutions, only imaginary ones.
In this question there are numerous information's that are given for getting the required answer. The most important of those informations is that the crew of workers required 20 minutes to pave 2/15 miles of the highway. It is required to find the portion of mile these workers will pave in 1 hour. We already know that 1 hour is equal to 60 minutes. This information will help to solve the problem.
In 20 minutes the crew of workers pave = 2/15 miles
In 60 minutes the crew of same workers will pave = (2/15) * (60/20)
= (2/15) * 3
= 2/5 miles
So the crew of workers working at the same rate will pave a portion of 2/5 miles in 1 hour.
The constant of proportionality represented by K will be 1/3 which is shown in the given graph.
<h3>What is the constant of proportionality?</h3>
Firstly, there is a proportional relationship.
Two values x and y are said to be in a proportional relationship if x = ky, where x and y are variables and k is a constant.
The constant k is called the constant of proportionality.
The proportional relationship between x and y can be written symbolically as
That middle sign is called a sign of proportionality.
In the given graph x line and y line have been graphed.
Since the relation between them has been represented by a straight line, so their relationship can be represented by
x = K × y
where K is the proportionality constant.
Now K =
=
= 1/3
therefore, the constant of proportionality will be 1/3.
