Answer:
the domain for this parabola is all real numbers
Answer:
The required explicit formula is A(n)= 4-4n
10th term of arithmetic sequence is (-36)
Step-by-step explanation:
Given arithmetic sequence is 8,4,0,-4,-8......
The arithmetic sequence is given by a,a+d,a+2d.......a+(n-1)d
Comparing both the sequence we get,
a=8 and a+d=4
For value of d:
d+a=4
d=4-8=(-4)
The explicit formula is given by : A(n)= a+(n-1)d
A(n)= a+(n-1)d
A(n)= 8+(n-1)(-4)
A(n)= 8-4n+4
A(n)= 4-4n
Therefore, The required explicit formula is A(n)= 4-4n
To find value of 10 th term:
Take n=10 in explicit formula
A(10)= 4-4(10)
A(10)= -36
Therefore, 10th term is (-36)

Answer:
I got 8, but I'm not sure.
Step-by-step explanation:
So I first did -6 + 5, and I got -1 as an answer. Then I did -1 plus 9 because both sides need to be equal. I wrote that x = 8 but that wasn't an option. I'm not sure if this was helpful and I'm really sorry if it's not.
