Answer:
![a_1=15](https://tex.z-dn.net/?f=a_1%3D15)
Step-by-step explanation:
We are talking about arithmetic progression.
Using the formula:
![a_n=a_1+(n-1) \cdot d](https://tex.z-dn.net/?f=a_n%3Da_1%2B%28n-1%29%20%5Ccdot%20d)
![a_7=a_1+(7-1) \cdot d](https://tex.z-dn.net/?f=a_7%3Da_1%2B%287-1%29%20%5Ccdot%20d)
![3=a_1+(7-1) \cdot (-2)](https://tex.z-dn.net/?f=3%3Da_1%2B%287-1%29%20%5Ccdot%20%28-2%29)
![3=a_1+(6) \cdot (-2)](https://tex.z-dn.net/?f=3%3Da_1%2B%286%29%20%5Ccdot%20%28-2%29)
![3=a_1-12](https://tex.z-dn.net/?f=3%3Da_1-12)

can i see the table please?
Answer:
The difference (in km) between what Kayden ran and what Jayden ran is, 7.867 km.
Step-by-step explanation:
The information provided is as follows:
- Kayden ran 8 km.
- Cayden ran half of distance Kayden ran.
- Isaac ran 1/5 of the distance Cayden ran.
- Jayden ran 1/6 of what Isaac ran.
So, using the given information it can be said that Cayden ran 4 km.
Then the distance Isaac ran is,
.
Then the distance Jayden ran is, ![0.8\ \text{km}\times\frac{1}{6}=0.133\ \text{km}](https://tex.z-dn.net/?f=0.8%5C%20%5Ctext%7Bkm%7D%5Ctimes%5Cfrac%7B1%7D%7B6%7D%3D0.133%5C%20%5Ctext%7Bkm%7D)
Compute the difference (in km) between what Kayden ran and what Jayden ran as follows:
![K-J=8-0.133=7.867](https://tex.z-dn.net/?f=K-J%3D8-0.133%3D7.867)
Thus, the difference (in km) between what Kayden ran and what Jayden ran is, 7.867 km.
Answer:
Step-by-step explanation:
y = -4x - <u>8</u>
Any equation with an equal slope will be parallel to the line
Example: y = -4x or y = - 4x + 8
As long as the equation has a different y-intercept and equal slope it will be parallel!
