Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -5x - 2
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = -5(3) - 2
- Multiply: f(3) = -15 - 2
- Subtract: f(3) = -17
The equation will be 6x - 4= 8.
Solve the equation: 6x - 4 = 8 + 4 + 4.
6x = 12. 6 6. x = 2

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) .
<u>Step-by-step explanation:</u>
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.
