Answer:

u= -3  v=11

Step-by-step explanation:

7u+2v=1     17u+6v=-9

-3(7u+2v=1)= -21u-6v=-3

-21u-6v=-3  +  17u+6v=-9 = -4u= -12

u=-3

7(-3)+2v=1

-21+2v=1

2v=22

v=11

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.
