Answer:
- neither
- arithmetic
- geometric
- arithmetic
- geometric
Step-by-step explanation:
Arithmetic sequences have a common difference. Geometric sequences have a common ratio.
The difference is found by subtracting a term from the next. If successive differences are all the same, they are "common."
The ratio is found by dividing a term by the one before it. If successive ratios are all the same, they are "common."
<h3>1.</h3>
There is no common ratio or common difference: neither.

__
<h3>5.</h3>
The common ratio is 1/8: geometric.
Answer:
A
Step-by-step explanation:
Price lowers so more people end up buying the product when it exceeds the demand.
Answer:
8
Step-by-step explanation:
Step-by-step explanation:
the area of this rectangle is
(10 + 2x)(8 + 2x) = 168
80 + 20x + 16x + 4x² = 168
4x² + 36x = 88
because for the whole length you need to add x twice (left and right). the same for the width (top and bottom).
Answer:
y=3/2x+5/2
Step-by-step explanation:
I used the Y2-Y1/X2-X1
In this equation you can see that there are 2 points (-5,-5) and (1,4)
If you substitute, you will get
4+5/1+5
9/6 and if you simplify this, you will get 3/2
Now that we have the slope, we just have to use y=mx+b
(I'm using the point (1,4)) 4=3/2(1)+b
4=3/2+b
5/2=b
