=(0.4n)(16n)
multiply 0.4 & 16 and n & n
=(0.4*16)(n * n)
=6.4n^2
Hope this helps! :)

4=9z
Step-by-step explanation:
Answer: Second option
Step-by-step explanation:
You need to make the multiplication of the function
and the function
. Then:

You need to apply the Distributive property:

Therefore, the domain will be all the number that make the denominator equal to zero.
Then, make the denominator equal to zero and solve for x:

Therefore, the domain is: All real values of x except 
Answer:
-2/5
Step-by-step explanation:
Your slope should be -2/5
In slope intercept for it should look like this, y= -2/5x+b.
Hope I helped
Answer:
y= -3x+2
Step-by-step explanation:
Parallel lines have the same slope. We can form an incomplete equation:
y= -3x+b
(make sure to see why the slope is -3)
We can plug in the coordinates of (2, -4):
-4= -3(2)+b
-4= -6+b
2=b
b is 2! We can form an equation: y= -3x+2
