Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
Yes, it is definitely a function. Although one might say that it is not a one to one or injective function because of the presence of (<span>-1,-2) and (6,-2).. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help.</span>
The answer would be x = 4 over g - 2

Answer:
Absolute decrease = 33 million
Relative decrease = 22.45%
Step-by-step explanation:
The number of CD's sold the previous year (2009) was 147 million, and in 2010 it was 114 million. The absolute decrease is 147 million -114 million = 33 million.
The relative decrease is just the percent decrease and it is:
33 million/147 million =22.45% decrease.
