We suspect the domain is values of x greater than 0 but less than about 100. At about x=70, the temperature matches that of the surface of the sun. Some experimental processes may produce higher temperatures, but a practical limit is certain to be x less than 4000, at which point the temperature exceeds the core temperature of the sun.
x2 =9
x4 =64
64-9 =55
4-2 = 2
55/2 = 27.5
average rate is 27.5, B is the answer
Answer:
x=12
Step-by-step explanation:
We can use cross products to solve
6 x
------ = ---------
18 36
6* 36 = 18x
Divide each side by 18
6*36/18 = 18x/18
6*2 = x
12 =x
