Answer:
x^(-5)+4x+1
given f(x)=4x+1 and g(x)=x^(-5)
Step-by-step explanation:
f(x)=4x+1
g(x)=x^(-5)
(f+g)(x) means you are just going to do f(x)+g(x)
or (4x+1)+(x^(-5))
There are absolutely no like terms so it can't be simplified. We can use commutative and associative property to rearrange the expression.
x^(-5)+4x+1

Answer:
1/2 or 0.5 dollars per kg of apples
The first thing to do is to find out how much a kg of apples sells for, since the question is only asking for the selling amount of a single kg. Nothing else. Each trip gets 300 dollars and delivers fifty packs. So each Pack, or P = 300/50, or P = 6 dollars
And each pack contains 12 kg of apples, so if P = 6 dollars and P = 12 kg of apples, then 6 dollars = 12 kg of apples
then 1 kg apples = 6/12, or 1/2.
So a single Kg of apples cost 0.5 dollars
Let the constant of variation be c.
We are given that y varies inversely with 2.5x, this means that:
y = (c) / (2.5x)
This can be written as:
2.5xy = c
Now, we a re given that y = 5.6 at x = 30.
Substitute with these values in the equation to get the value of c as follows:
2.5xy = c
2.5(30)(5.6) = c
c = 420
Therefore, the equation that describes the relation is:
2.5xy = 420
