Answer:
x = 12
Step-by-step explanation:
Equation: 0.52(x) + 0.72(4) = 0.57(x + 4)
0.52(x) + 0.72(4) = 0.57(x + 4) 
Multiply
0.52x + 2.88 = 0.57x + 2.28 Subtract 0.52x from both sides
2.88 = 0.05x + 2.28 Subtract 2.28 from both sides
0.6 = 0.05x Divide all sides by 0.05
x = 12

Answer
No
Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function
Answer:
A
Step-by-step explanation:
the arc of a circle is 85° the same as the central angle 85
so the range is between 0 and 90 degrees
π/2=90 degrees
0 and π/2
The inverse function of f(x) is 
and the domain is x > 6
<h3>How to determine the inverse function?</h3>
The function is given as:
f(x) = x^2 + 6
Rewrite as:
y = x^2 + 6
Swap x and y
x = y^2 + 6
Subtract 6 from both sides
y^2 = x - 6
Take the square root
Rewrite as:
Hence, the inverse function of f(x) is and the domain is x > 6
