Step-by-step explanation:
sorry I'm bad at explaining things
From the given information it is clear that the amount of time, or in other words the number of hours, , required to wash number of cars are related such that more the number of cars then more is the number of hours to wash those cars.
Thus, we have a relationship between and as:
.................(relationship 1)
Now, we know that the number of hours is inversely proportional to the number of students. Thus we have:
.................(relationship 2)
Thus combining the two relationships, (relationship 1) and (relationship 2), we get:
This is the complete relationship between all the three variables involved.
This can be converted into an equation by replacing the proportionality sign by the equal to sign and constant of proportionality (say ) as:
The equation of the median in standard form is; 9y - 38x = 179.
<h3>What is the equation of the media in standard form?</h3>
It follows from the task content that the point D is the midpoint of segment BC; Hence, the coordinates of point D given the coordinates of B and C above are given as; D(-13, -35).
The equation of the median which is the line joining points A and D is therefore determined as follows;
Slope = (-35-3)/(-13-(-4)) = 38/9
38/9 = (y-3)/(x+4)
9y -27 = 38x + 152
9y - 38x = 179.
