Answer:
Step-by-step explanation:
The sum of a number and 9 is adding of any variable to 9.
E.g the sum of 8 and 7
8+7=15
We can also have the sum of two unknown numbers, we can let the first number be x and the second number be y, then the sum of the two unknown will be (x+y).
So, let apply this to the question
The sum of a number and 9, since we don't the number, let the number be n, then the sum of the number and 9 will be (n+9)
Then the correct option is B which is n+9
The answer is -93, here is the work :)
Answer:
Step-by-step explanation:
Given [Missing from the question]

Solve
Using factorization, we have:
Expand 2x
Factorize
Factor out 2x - 1
Split:
In both cases, solve for x

<span>Linear regression is a method of finding the linear equation that comes closest to fitting a collection of data points.
</span>The better the choice of line, the closer the predicted values will be to the observed values.
The differences between the data pints (observed values) and the estimated (pedicted) regression line is called the <span>residue.
</span>Residue = Observed Value -<span> Predicted Value</span>
You are factoring one or more linear expressions (but are not factoring variables).
2.4n+9.6 can be divided by 2.4 and then the result mult. by 2.4:
2.4n+9.6 = 2.4 [ n + 4 ]
Also: -6z+12= 6 [ -z + 2 ] Here I have simplified linear functions but factoring out common constant coefficients (not variables).
