Answer:
-6x + 21
Step-by-step explanation:
9 - 3(2x - 4)
9 - 6x + 12
-6x + 21
Take 3÷2.6=1.153846repeating. So around $1.15. To check you can take the decimal point times by 2.6 and it will give you three.
Given:
The expression is:

It leaves the same remainder when divided by x -2 or by x+1.
To prove:

Solution:
Remainder theorem: If a polynomial P(x) is divided by (x-c), thent he remainder is P(c).
Let the given polynomial is:

It leaves the same remainder when divided by x -2 or by x+1. By using remainder theorem, we can say that
...(i)
Substituting
in the given polynomial.


Substituting
in the given polynomial.



Now, substitute the values of P(2) and P(-1) in (i), we get




Divide both sides by 3.


Hence proved.
(0,0.5) and (10,10)
You always start at the beginning point and the end point and what ever points hit that line, great! That is why it is best fit and not connect the dots.
Hope I helped!
