Answer:

x = 24

Step-by-step explanation:

x -2(x + 4) = 16

x - 2x - 8 =16

- x - 8 = 16

- x = 16 + 8

-x = 24

x = 24

Evaluate the function fx = 4 * 7^t for x= -1 and x=2
Alex73 [517]
Well what i think you're asking here...I apologie if I'm wrong but what I did was 

f(-1) = 4 * 7^t = 4/7 

and 

f(2) = 4 * 7^t = 196.

Is this what you wanted if not I can...try another way.

Step-by-step explanation:

\sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha)

Use the identity

\sin^2 \theta = \dfrac{1 - \cos 2\theta}{2}

on the left side.

\dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha)

\dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha)

Now use the identity

\sin \theta = \cos(\frac{\pi}{2} - \theta)

on the left side.

\dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha)

\frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha)
