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.
One of the ways of dividing polynomials is by synthetic division
The divisor of the synthetic division is x + 5
<h3>How to determine the divisor of the division</h3>
From the question, we understand that:
Entry -5 is on the outside to the left of the shape
The entry represents the zero of the divisor.
Next, we set this entry to the variable (assume the variable is x)
So, we have:

Add 5 to both sides

Hence, the divisor of the synthetic division is x + 5

No, 21 is a multiple of 7
8x + 4y = 20
4y = 20 - 8x
y = 5 - 2x
1/2m-3/4n=16
1/2m-3/4(8)=16
1/2m-6=16
1/2m=22
m=44
I hope this helped!
