we have that

substitute the values and solve for h


Answer:
a(n) = 13 - 2n
Step-by-step explanation:
The explicit formula variables are a(n) = a(1) + d (n - 1). The a(1) is your number you started out with, and the d is the common difference. From the recursive formula example, you see that your first number is 11 and your difference is -2.
1. Plug the numbers into the equation : a(n) = 11 - 2 (n - 1)
2. Distribute: a(n) = 11 - 2n + 2
3. Add like terms: a(n) = 13 - 2n
If you want to double check, you can plug 1 into n and see if you get 11. I did this, and I did so it should be correct. Hope this made sense! Have a great day :)
Answer:
Independent: Time, Dependent: Distace
Step-by-step explanation:
The x Axis is usually independent, it lays on the ground. The Y-axis depends on the x-axis to hold it up up. < little way to remember
(8x + 7) - (2x - 3)
(8x + 7) + (-2x + 3)
combine like terms
8x - 2x and 7 + 3
6x + 10
