Find the point b on ac such that the ratio of ab to bc is 3: 1

and

Step-by-step explanation:

Let us assume that the coordinates of a and c are respectively and  , and the coordinates of point b are  .

So, we have to express the coordinates of b in terms of the coordinates of a and c provided the ratio of segment ab to bc is 3 : 1.

Now, we know, the formula of coordinate geometry that if there are two known points P   and Q   and the point R divides PQ line segment in m : n ratio internally, then the coordinates of R will be given by .

Therefore, using this formula we can write  

and  

(Answer)

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
