Answer:

see explanation

Step-by-step explanation:

If f(x) and f^{-1} are inverse functions, then

f(f^{-1})(x) = x

Thus substitute x = f^{-1} (x) into f(x)

f(\frac{x+6}{5} )

= 5 (\frac{x+6}{5} ) - 6

= x + 6 - 6

= x

Thus f(x) and f^{-1} (x) are inverse functions

Lorico [155]

Answer:

  y +9 = 15(x -2)

Step-by-step explanation:

  y -k = m(x -h) . . . . . . for slope m and point (h, k)

Here, you are given m=15 and (h, k) = (2, -9). Putting these values into the form gives the equation ...

  y +9 = 15(x -2)

If two triangles have three corresponding angles and three corresponding sides that are equal in measure, are the two triangles
nikitadnepr [17]
Yes, they are.

If the triangles have three corresponding angles equal means that they are either similar or congruent.

The definition of congruent means that the sides have the same length. That is precisely what the statement says.

So, being the lengths of the corresponding angles the same the two triangles are identical, this is they are congruent.
