Answer:
Step-by-step explanation:
If the 2 is an exponent, it needs to be written as ^2.
(5+√3)² = 5² + 10√3 + 3 = 28 + 10√3
Answer:
Step-by-step explanation:
2x+5<9
= 2x<9-5
= 2x<4
*divide both sides by 2
= x<2
Answer:
Step-by-step explanation:
f * h / h = f
p / r * r = p
k + g - g = k
a + b - b = a
<span>We want to show that f(g(x)) = x and g(f(x)) = x.
So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly.
Let's begin with f(g(x))
Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x
What then is f(4/x) equal to? Use the definition of f.</span>
