1/2 = 2/4 because if you divide 2/4 by 2 you get 1/2.

Answer:

C) $-\frac{47}{49}$

Step-by-step explanation:

By the cos double angle formula, we know $\cos(2\theta)=2\cos^2\theta-1.$ Substituting $\cos \theta$ into the formula, we get

$\cos(2\theta)=2(-\frac{1}{7})^2-1\\~~~~~~~~~~=\frac{2}{49}-1\\~~~~~~~~~~=\boxed{-\frac{47}{49}}$ .

The answer is C.

What is the value of x in the equation 2(x+3)=4(x-1)

Nina [5.8K]

Firstly, expand the equation.
$2(x + 3) = 4(x - 1) \\ 2x + 6 = 4x - 4$

Next, move the variable x to the left and all the constant to the right.
$2x + 6 = 4x - 4 \\ 2x - 4x = - 4 - 6 \\ - 2x = - 10$

Then, solve for x.
$- 2x = - 10 \\ x = \frac{ - 10}{ - 2} \\ x = 5$
