Answer:
yes
Step-by-step explanation:
The graph of a proportional relationship is a straight line graph passing through the origin.
Since the graph here does this then there is a proportional relationship between x and y
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Find y:
8x-y=40
y = 8x - 40
slope = 8
Answer: The cost of renting the car for one day and driving at 75 miles = $ 47.5 .
Step-by-step explanation:
GIven: Daily cost of renting car = $ 25.00 + $0.30 per mile driven
Let x = Total distance traveled ( in miles).
Then total cost of renting (in $)= 25+0.30x
For x= 75 miles
The total cost of renting (in $)= 25+0.30(75)
=25+22.5
= $47.5
Hence, the cost of renting the car for one day and driving at 75 miles = $ 47.5
