Answer:
The function is represented by
.
Step-by-step explanation:
In this case, we must observe that total cost of the dog (
) is the sum of two components: i) <em>Fixed cost</em> (
) - Adoption fee, ii) <em>Variable cost</em> (
) - Daily cost of feeding the dog, both measured in US dollars.
In addition, we suppose that variable cost is directly proportional to the number of days that Kirstin owns her dog. That is:


Where:
- Number of days that Kirstin owns her dog, measured in days.
- Daily feeding costs, measured in US dollars per day.
If
, then:

The function is represented by
.
Answer: x=3
Step-by-step explanation: Subtract 2 from both sides and subtract 5x from both sides. Then you'll end up with 6 = 2x. Then divide through by 2 on both sides and you're left with x=3.
This might be wrong, but I think it's 15. Again, sorry if I'm wrong.
Start with the point-slope formula shown at the top in red.
Now, substitute your slope and coordinates in the formula.
Then distribute and combine lie terms.
Finally, add 2x to both sides to get your equation in standard form.
