Answer:
F = 100 + 0.1d
Step-by-step explanation:
- Initial charge is $100
- Price for climbing 3000 m = 400
<u>Then equation to find a fee per vertical distance:</u>
- 100+3000x = 400
- 3000x = 300
- x = 300/3000
- x = $0.1 per/m
So the fee for climbing vertical distance is $0.1 per meter.
- Vertical distance = d m
- Total cost = F
<u>Then, required equation is:</u>
Answer:

Step-by-step explanation:
Given the slope and another point, simply plug them into the point-slope formula to find your y-intercept.

Now that we've found your y-intercept, we have the original equation. To find the perpendicular equation, you need the opposite reciprocal of your slope.
To find the 'opposite,' change your slope's sign. Since your slope is positive
, the opposite is
.
To find the 'reciprocal,' flip your fraction. This will make your slope
.
Your final equation is:

Answer: A
Step-by-step explanation:
Divide both sides by their LCD, 2
2/4 = 1/2
1/2 is irreducible
