105.5x100/120=87.91so 100-88 = 22%
Answer:
C
Step-by-step explanation:
3x-y=14
4x+y=21
add
7x=35
x=35/7=5
4×5+y=21
y=21-20=1
so (5,1 ) is the solution.
Answer:

Step-by-step explanation:
First, let’s check to see if the direction vector is a unit vector:

It’s not a unit vector. therefore let's divide the vector by its magnitude in order to convert it into a unit vector:

Now, the directional derivative is given by:

So let's calculate the partial derivates:



Therefore:

Six times a number plus five is equal to seventeen.
Five added to the product of six and a number is seventeen.
