A = P + SI
A-P = SI
5425-5000 = 425
THEREFORE THE SIMPLE INTRESTE IS $425
SI = PTR/100
425 = 5000×1×R/100
425×100/5000×1=R
425×100÷5,000×1 = 8.5%
THEREFORE THE RATE IS 8.5%

Why?</h2>
To composite functions, we need to evaluate functions in another function(s), for example:
Given f(x) and g(x), if we want to calculate f(x) composite g(x), we need to evaluate g(x) into f(x).
So, we are given the functions:

And we are asked to calculate g(x) composite f(x), and then evaluate "x" to 0, so, calculating we have:

Now that we have the composite function, we need to evaluate "x" equal to 0, so:

Hence, we have that:

Have a nice day!
Y+4 would complete the rule for this translation.
Answer:
4x+1
Step-by-step explanation:
Since you're finding (f+g) (x), it means you are adding f(x) and g(x) together.
so you add: (3x-1) and (x+2)
combining like terms, you get 4x and 1, which means (f+g)(x)= 4x+1
