X = 8 since the two triangles are congruent, measure of angle J is the same of the measure of angle T ..therefore you can set up: 97+37+4x+14 = 180..(total degrees in a triangle). now solve for x
7/y....the coefficient of y is 1
any time u have a variable by itself, whether it is x or y or any letter, the coefficient is gonna be 1

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.
