Answer:
15
Step-by-step explanation:
f(x) = 5x + 40
…………………………
when x = -5
f(-5) = 5(-5) + 40
= -25 + 40
= 40 - 25
= 15
Answer:
(4,1), (-4,1), (4,6), (-4,6)
Step-by-step explanation:
Here can be identified two points with the same 'y' value: (4,1), (-4,1)
it means that there is a line passing by y=1
Same for (4,6), (-4,6): it means that there is a line passing by y=6
Now find the distance between two points in both cases
Answer:
13/18
Step-by-step explanation:
Answer: $340
Step-by-step explanation:
To identify the cost of renting the boat for 30 hours, breakdown the 30hours into specific renting hours
i.e 30 hours = (7 hours + 10 hours + 13 hours)
Then calculate each of the renting cost based on the hour breakdown given above
- Since the Cost of renting a fishing boat is $25 per hour for the first 7 hours, then (25 x 7 hours = $175)
- For the $10 per hour for the next 10 hours, then (10 x 10 hours = $100)
- and for $5 per hour for any additional hours. (5 x 13 additional hours = $65)
Now, sum up all of the cost of the hourly breakdown
i.e 30 hours = (7 hours + 10 hours + 13 hours)
= $175 + $100 + $65
= $340
Thus, the cost of renting the boat for 30 hours is $340
Answer:
f(2) = 0 and f(6) = -4
Step-by-step explanation:
First, find f(x) when x = 2
Plug in 2 as x in the function:
f(x) = -(x - 2)
f(2) = -(2 - 2)
f(2) = -(0)
f(2) = 0
Next, find f(x) when x = 6. Plug in 6 as x in the function:
f(x) = -(x - 2)
f(6) = -(6 - 2)
f(6) = -(4)
f(6) = -4
So, f(2) = 0 and f(6) = -4
