A plumber charges a fixed fee for coming to your house, then charges a fixed amount per hour on top of this. X= the time the job
1 answer:
Step-by-step explanation:
This problem expects us to model the equation for the total cost of the services of the plumber given the conditions stated.
Say the fixed amount charged for coming to your house is $10
say the fix amount charged per is $3
and the time spent to do the job is X
Hence the scenario can be modeled as
the equation is similar to the equation of a straight line

Answer:
We conclude that option 'C' i.e. 1/3x+1=2x-4 is the correct option.
Step-by-step explanation:
From the given graph, it is clear that the two lines meet at the point (3, 2).
In other words,
- at x =3, y = 2
Thus,
The point of intersection between two lines is:
(x, y) = (3, 2)
Here:
x = 3 is the value of the x-coordinate
y = 2 is the value of the y-coordinate
Now, checking the equation i.e. 1/3x+1=2x-4 to determine whether the equation contains the correct value of x-coordinate or not.
Subtract 1 from both sides
Simplify
subtract 2x from both sides
Simplify
Multiply both sides by 5
Simplify
Divide both sides by -5
Simplify
Therefore, the value of x = 3
Conclusion:
We conclude that option 'C' i.e. 1/3x+1=2x-4 is the correct option.
