Answer:

{f}^{ - 1}(x)  = 2x + 8

Step-by-step explanation:

f(x) =  \frac{x}{2}  - 4 \\ \\  y = \frac{x}{2}   - 4 \\ \\ y =  \frac{x - 8}{2}   \\  \\ x = 2y + 8 \\  \\  {f}^{ - 1} (x) = 2x + 8

What the answer now answer only if now answer corry
goblinko [34]

Answer:

Approximately 11.5 units.

Step-by-step explanation:

We need to find the side opposite to ∠W. We are given the two angles ∠W and ∠X. We are also given that Side X is equal to 7. Therefore, we can use the Law of Sines.

Now, like last time, use the Law of Sines:

\frac{\sin(V)}{v}=\frac{\sin(W)}{w}=\frac{\sin(X)}{x}

We can ignore the first term. Plug in 144 for ∠W, 21 for ∠X, and 7 for <em>x</em>.

\frac{\sin(144)}{w}=\frac{\sin(21)}{7}

Cross multiply:

7\sin(144)=w\sin(21)\\w=\frac{7\sin(144)}{\sin(21)} \\v\approx11.4812\approx11.5

to prove if you're right (9×2=18)

if it's 11 baseball games then 11×2=22

Hope It Helps ☺️
