Answer:
(a) (f+g)(x) = √(2x) +x²
(b) (f-g)(x) = √(2x) -x²
(c) (f·g)(x) = x²√(2x)
(d) (f/g)(x) = (√(2x))/x²
Step-by-step explanation:
These are all about the meaning of the notation (f <operator> g)(x). When the operator is an arithmetic operation (addition, subtraction, multiplication, division), the notation means the same thing as ...
f(x) <operator> g(x)
__
(a) (f+g)(x) = f(x) + g(x)
(f+g)(x) = √(2x) +x²
__
(b) (f-g)(x) = f(x) -g(x)
(f-g)(x) = √(2x) -x²
__
(c) (f·g)(x) = f(x)·g(x)
(f·g)(x) = x²√(2x)
__
(d) (f/g)(x) = f(x)/g(x)
(f/g)(x) = (√(2x))/x²
solved what I didn't solve anything
Answer:
I believe the final answer is x=3
Step-by-step explanation:
when trying to solve equations, always sort things out and prioritize things, that way it's easier to get to the final answer.
x+2x-5=4
3x-5=4 just move the -5 to the other side and make it a positive
3x=9
x+y=4
y=1
3+1=4
Given 
and 
(say).
Then,
From the above 3 equations,
From the equations, we get
Since , the negative value is rejected.
