What is the inverse of the function??
Firlakuza [10]
\(\begin{matrix}
y=ln(x+3)\\
e^y=x+3\\
e^y-3=x\\
swap ~x~and~y\\
 \huge\underline{y=e^x-3}}
 \end{matrix}\)


To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:

- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).

- Swap x and f(x).

- The result is the inverse of the original function f^{-1}(x).

-------------------------

Apply that on your function
\(\begin{matrix}
y=ln(x+3)\\
e^y=x+3\\
e^y-3=x\\
swap ~x~and~y\\
 \huge\underline{y=e^x-3}}
 \end{matrix}\)

Answer:

80*

80*

75*

120*

Step-by-step explanation:

both angle 1 and 2 for the first image have the same value as  the other angle of 80* because it is a set of parallel lines and one line going through it.

1 on the next set of images is 75* because is is an alternate exterior angle.

2 of the last set of images is 120* because it is same side interior angles.

Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationa
Dimas [21]
These equations do match up. All you have to do is find the solution to the first equation. After that, plug in that solution to the second equation. If it makes the equation true, then the equations match. 

Hope this helps!
