Find 
First, we calculate the inverse function

Express f(x) as y

Swap the positions of x and y

Solve for y: Add 4 to both sides


Square both sides

Divide both sides by 2

Express y as an inverse function

Next, solve for: 
Substitute 6 for x




One possible way:
-86+(4*12)=-38
-86 is the number where the diver is. 86 feet below the surface.
4*12 is the total number of feet he has ascended in 12 minutes.
Because he is ascending, so you add 4*12 (or 48) to -86.
The answer is -38, meaning he's 38 feet below the surface.
The diver is now 38 feet below the surface.
Hope this helps.
Answer:
7 Caterpillars
Step-by-step explanation:
14/2
ABC = XYZ by SAS
AB = XY - Side
A = X - Angle
So you want to find another congruent <em>side</em>.
Removing the taken possible side, two sides can be congruent.
Either :
BC = YZ
<em>OR</em>
AC = XZ
Ok so first what you gotta do is carry the 1 to the 7 which makes 8 minus 1 is 7 so your answer is D
