To rewrite as a function of x (f(x)), write the equation so that y is by itself on one side of the equal sign and an expression involving only x is on the other side.
f (x) = - x^4
Your answer is 25% because a change from 16 to 20 represents a positive change (increase) of 25%
Hello there!
I see you got some work done already, but I guess you just wanted to double check! :)
3n + 8 = 20
3n = 20 -8 (Subtract 8 on both sides).
3n = 12 (Combine like terms).
n = 4 ( divide both sides by 3)
There you have your answer! :D
Hope this helped!

That is an irrational number
Answer:
radius ≈ 17.0 units
Step-by-step explanation:
The radius is the distance from the centre of the circle to a point on it.
Calculate the radius r using the distance formula
r = 
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (7, 12)
r = 
= 
= 
= 
≈ 17.0 ( to the nearest tenth )
