Step-by-step explanation:
Taking the succession:
You can multiply and divide by 1-r without chaging the result:
Distributing the upper part of the fraction you have:
As can be seen all the intermediate members will be canceled by a same member with opposite sign, only 
will be left so:

The reason why partitioning and fractioning are different is because; The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
<h3>Why is partitioning different from fractioning?</h3>
It follows from the task content that a close analysis of the statement of ratios; 1:3 implies that the whole is divided into four parts; 1+3 = 4.
On the contrary, one-third simply means 1 out of 3 equal parts of the line.

Answer:
(2,7) and (-1,4)
Step-by-step explanation:
solve for the first variable in one of the equations then
substitute the result into the other equation.
Step-by-step explanation:
an open (empty) point means the point itself is not included.
a closed (filled) point means the point itself is included.
the x values going from -3 (not included) to -1 (included) means
-3 < x <= -1
so, the second answer is correct.
