Amount of money charged by Luigi as fees = $140
Hourly rate of Luigi for each contract = $25
In the question there are more important information's already provided. Let us write them down first.
Total amount charged by Luigi for a project = y
Number of hours worked on the project by Luigi = x
Then the equation can be written as
y = 140 + 25x
Now
The amount earned by Luigi after 10 hours = 140 + (25 * 10) dollars
= 140 + 250 dollars
= 390 dollars
So the amount earned by Luigi after 10 hours is $390. I hope the procedure is clear enough for you to understand.
Yes rational expression and its simplified forms are equivalent.
Rational expression are those that contain fractions.
Example:
25/50 is a rational expression but it is not yet in its simplest form.
25/50 ⇒ 5/10 ⇒ 1/2
1/2 is the simplest form of 25/50.
They are equivalent:
1/2 = 25/50
1*50 = 2*25
50 = 50
or
1/2 = 0.50
25/50 = 0.50
Slope = (-3 - 1) / (4 -4) = -4
