Step-by-step explanation:
-cz+6z-tz=83
z(-c+6-t)=83
z(-c+6-t)/(-c+6-t)=83/(-c+6-t)
z=83/(-c+6-t)
Direct variation is y = kx
Inverse variation is y = k/y
if z varies directly with x, then the equation would be z = kx
if z varies inversely with y^2 then the equation would be z = k/y^2. Combining, these two, we have z = kx/y^2
We use the first set of values to find the constant k:
x = 2, y = 5, z = 8:
8 = 2x/25, k = 100. Now we use the second set of values to find z:
x = 4, y = 9, k = 100 and z is unknown:
z = (4X100)/9^2
z = 400/81--> this is your final final answer.

An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
I hope this helps!

I did this really quick so I hope all the answers are right, and double check them if you have time just in case
Answer: yes it does
2x= 8
x= 8/2
x=4.
