Both are correct, since 4/6 is simplified to 2/3.
Well, since it's already set up, all we do is divide -6 by 3/4 to get our x
So that means x=-8
Answer:
quadratic
Step-by-step explanation:
The x-values are sequential, so we can look at the y-values.
Differences from one to the next are ...
-7, -1, 5, 11, 17
And the differences of these numbers are ...
6, 6, 6, 6
When <em>second</em> differences are constant, the sequence can be produced by a <em>second</em>-degree (quadratic) polynomial.

Here, that polynomial is ...
y = 3x² +2x -1
The regression functions of a graphing calculator can help you find the appropriate formula.
Answer:
20.7 --> 21
9.18 --> 9
21x9 is 189, thus the estimated product is 189.
