Answer:
Open dot on 4 with arrow going to the right.
Step-by-step explanation:
4 is open because it is not part of the set.
Answer: 4x+10y
you can't simplify 4x+10y
Answer:

You gave the explicit form.
Step-by-step explanation:
You gave the explicit form.
The recursive form is giving you a term in terms of previous terms of the sequence.
So the recursive form of a geometric sequence is
and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
r is the common ratio and can found by choosing a term and dividing by the term that is right before it.
So here r=-3 since all of these say that it does:
-54/18
18/-6
-6/2
If these quotients didn't match, then it wouldn't be geometric.
Anyways the recursive form for this geometric sequence is

?
Step-by-step explanation:
Answer:
32.94
Step-by-step explanation:
24(.22) [Both Sales tax and tip.] = $5.28 Add to the 27. You get $32.28
Or, you could be estimating based on the delivery fee too. Which the would be this:
27(.22) = 5.94 + 27 = 32.94
