Ok so f(x) and g(x) are the same thing as y. this means that you can solve these equations the same as any other multi-step equation. the only difference is if they have a number other than x in the parentheses. if they have a number you will just replace the x’s in the equation with the number in the parentheses.
example:
regular equation equation with f(4)
f(x)=2x+1 f(4)=2(4)+1

Answer:
r=1.91
Step-by-step explanation:
hopefully this helps...
Using the formula
C=2πr
Solving for
r= C/2π = 12/2·π = 1.90986
Answer:
X=5.66 or 5.65685424949
Y=4
Step-by-step explanation:
Since this is a 45,45,90 triangle, the y is also 4.
Then the x is y^2+4^2.
That means that it is 16+16=32
Now you have to square 32 which gives you 5.66
This is a proportion problem.
z 4
--- = ----
12 5
We can cross multiply and divide.
5z = 48
z = 9.6
Hope this helps!
