The solution of the equation f(x) = g(x) are x = 3.055 or x = -6.055 if the f(x) = -x + 2.5 and g(x) = x² +2(x - 8)
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
f(x) = -x + 2.5
g(x) = x² +2(x - 8)
f(x) = g(x)
-x + 2.5 = x² +2(x - 8)
After simplification:
x² + 3x - 18.5 = 0
After solving, we get:
x = 3.055 or x = -6.055
Thus, the solution of the equation f(x) = g(x) are x = 3.055 or x = -6.055 if the f(x) = -x + 2.5 and g(x) = x² +2(x - 8)

Answer: The correct option is
(E) 80,000.
Step-by-step explanation: Given that after adding 4,000 gallons of water to a large tank that was already filled to of its capacity, the tank was then at of its capacity.
We are to find the number of gallons of water that the tank hold when filled to capacity.
Let the tank can hold x gallons of water when filled to capacity.
Then, according to the given information, we have
Thus, the required capacity of the tank is 80,000 gallons of water.
Option (E) is CORRECT.
the answer is 1/8 because since one toss would be 1/2 then 1/2 * 1/2 *1/2= 1/8
