Answer:
B
Step-by-step explanation:
We are given the function:
And we want to determine the value of:
Let this value equal <em>a</em>. In other words:
Then by the definition of inverse functions:
Hence:
Solve for <em>a: </em>
By the Zero Product Property:
Hence:
Thus, f(9) = 225. Consequently, f⁻¹(225) = 9.
In conclusion, our answer is B.
This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)
So symmetric property should be your answer
Hope this helps
Answer:
The answer is y = 2x - 3.
Step-by-step explanation:
Move 2x to the right side of the equation by adding it to both sides:
-2x + y + 3 = 0
<u>+ 2x + 2x</u>
y + 3 = 2x
Then, move 3 to the right side of the equation by subtracting it form both sides:
y + 3 = 2x
<u> - 3 - 3</u>
y = 2x - 3
