Answer:
y = 4x +1
Step-by-step explanation:
6x + 1 = y + 2x
First you need to solve for y, so then you need to
1. Combine like terms
So since there isn't anything to combine we can more on.
2. Make Y by itself
You need to subtract the 2x from both side to get the answer
y = 4x +1
Answer:
a)
.
b) 
Step-by-step explanation:
Given a function
, this function has the following gradient:
.
(a) find the gradient of f
We have that
. So


.
.

(b) find the directional derivative of f at (2, 4, 0) in the direction of v = i + 3j − k.
The directional derivate is the scalar product between the gradient at (2,4,0) and the unit vector of v.
We have that:

.

The vector is 
To use v as an unitary vector, we divide each component of v by the norm of v.

So

Now, we can calculate the scalar product that is the directional derivative.
