Help wanted ill do brainliest!!
Pani-rosa [81]

Answer:

x=-1

Step-by-step explanation:

0.5 ( 5 - 7x ) = 8 - ( 4x + 6 )

<u>- Distribute 0.5 by 5 and -7x</u>

2.5 - 3.5x = 8 - ( 4x + 6 )

Second- Distribute the invisible one into 4x and 6

2.5 - 3.5x = 8 - 4x - 6

- Combine like terms: Subtract 6 from 8

2.5-3.5x= - 4x + 2

-Add 4x from both sides of the equation

2.5 + 0.5x = 2

-Subtract 2.5 from both sides of the equation

0.5x = 2- 2.5

0.5x = -0.5

-Then divide each side by 0.5x

<u>0.5x</u>  = <u>-0.5</u>

0.5      0.5

-Cancel the common factor of 0.5

x = <u>- 0.5</u>

      0.5

-Divide -0.5 by 0.5

X = -1

Evaluate the following trigonometric expression, using the principal value for the cosine
Maslowich

Given:

The expression is

\tan (\cos ^{-1}(-\dfrac{1}{2}))

To find:

The value of given expression.

Solution:

We have,

\tan (\cos ^{-1}(-\dfrac{1}{2}))

=\tan (\pi-\cos^{-1}(\dfrac{1}{2}))          [\because \cos^{-1}(-\theta)=\pi -\cos^{-1}\theta]

=\tan (\pi-\cos^{-1}(\cos \dfrac{\pi}{3}))      [\because \cos \dfrac{\pi}{3}=\dfrac{1}{2}]

=\tan (\pi-\dfrac{\pi}{3})

=-\tan (\dfrac{\pi}{3})                 [\because \tan(\pi-\theta)=-\tan \theta]

=-\sqrt{3}         [\because \tan \dfrac{\pi}{3}=\sqrt{3}]

Therefore, the value of given expression is -\sqrt{3}.
