Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and z, represent an inverse variation if it can be expressed in the form 
or 
step 1
Find the value of k
For x=6, z=2
substitute
therefore
The equation of the inverse variation is equal to
step 2
What is the value of z when x=13
substitute the value of x in the equation and solve for z

Answer:
7000
Step-by-step explanation:
21000/0.667
=14000
21000-14000
=7000
Interchange the x and y and solve for the resulting y.
x = 4y^2 - 2
(x + 2) = 4y^2
(x + 2)/4 = y^2
+/- sqrt(x + 2)/2 = y
