Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
Forth degree trinomial because we have a number that’s to the exponent of four and we have 3 terms.
You would isolate the variable for ex
2x+3=9
2x=9-3
2x=6
x=3
Answer:
3.2 because 16 divided by 5 is 3.2
