Answer:
f(1) = 8
Common ratio: 0.5
Step-by-step explanation:
f(1) means the firs term in a sequence.
In the function f(n), represented by 8, 4, 2, 1, .., the first term is 8.
f(1) = 8
To find the common ratio, divide any term by the term before it.
We can use any two of the given terms in the sequence EXCEPT for 8 because it is the first term and does not have a term before it.
I choose to divide the second term by the first term:
4/8 = 1/2 = 0.5
Answer:
(xy^3z,4)
Step-by-step explanation:
I think the answer would be 1.8
x-17= 23
move -17 to the other side
sign changes from -17 to +17
x-17+17= 23+17
x= 23+17
Answer:
x= 40
