What is the vector sum of (7,5) and (13,-5)

The vector sum of  two vectors as (7,5) and (13,-5) is given by which can be written in point form as  (20,0) .

Step-by-step explanation:

Here we have , two vectors as (7,5) and (13,-5) Which are represented as :

Addition of vector is as same as normal addition of integers as :

⇒

⇒

⇒ ,

where i & j are the unit vectors in direction x-axis and y-axis respectively.

The vector sum of  two vectors as (7,5) and (13,-5) is given by which can be written in point form as  (20,0) .

Vector sum of the given points is 20 i.

Step-by-step explanation:

Vector sum is like the sum of the numbers with the same coefficients here i component and j component.

That is the given points can be written as,

(7,5) → 7 i + 5 j

(13,-5) → 13 i - 5j

Now we have to add the terms with the same coefficients to find the vector sum as,

7 i + 13 i + 5 j - 5 j = 20 i + 0 j
