Cross multiply
20(x+1)=14(x-1)
20x+20=14x-14
Subtract 14x on each side giving you
6x+20=-14
Subtract 20 on each side giving you
6x=-34
x=-34/6. Simplifying that you get x=-17/3. I hope this helps!!!

Answer:

X=-17/3

Step-by-step explanation:

x+1/x-1 = 14/20

20x+20=14x-14

Subtract 20 from both sides

20x+20-20=14x-14-20

Simplify

20x=14x-34

Subtract 14x from both sides

20x-14x=14x-34-14x

Simplify

6x=-34

Divide both sides by 6

6x/6=-34/6

Simplify

X=-17/3

Thank you for letting me help!!

Which angles are coterminal with −6π5 ? Select each correct answer. 14π/5 −16π/5 −π/5 −11π/5
wariber [46]
ANSWER

-  \frac{16 \pi}{5}  \: and \:   \frac{14\pi}{5}


EXPLANATION

Coterminal angles are angles in standard position that have the same terminal side.


To find an angle in standard position that is coterminal with

-  \frac{6 \pi}{5}

We add or subtract multiples of
2 \pi

The first addition gives,

-  \frac{6 \pi}{5}  + 2 \pi =  \frac{4 \pi}{5}


We add the second multiple to get,

-  \frac{6 \pi}{5}  +2( 2 \pi )=  \frac{14 \pi}{5}

Since this is the maximum value among the options, we end the addition here.


Let us now subtract the first multiple to get,


-  \frac{6 \pi}{5}  -   2 \pi =   - \frac{16 \pi}{5}


We end the subtraction here because this is the least value among the options.


Therefore the angles that are coterminal with
-  \frac{6 \pi}{5}
are

-  \frac{16 \pi}{5}  \: and \:   \frac{14\pi}{5}
