Answer:

y=-3x+20

Step-by-step explanation:

3/4x+1/4y=5

-3/4x           -3/4x

1/4y=5-3/4x

divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)

Your answer is y=-3x+20

Help please explain ​
MatroZZZ [7]

Given:

\sin^{-1}\left(\dfrac{5}{8}\right)=A

To find:

The correct equivalent equation.

Solution:

We have,

\sin^{-1}\left(\dfrac{5}{8}\right)=A

Taking sin on both sides, we get

\sin \sin^{-1}\left(\dfrac{5}{8}\right)=\sin A

\dfrac{5}{8}=\sin A                      [\because \sin (\sin^{-1}\theta )=\theta]

Interchanging the sides, we get

\sin A=\dfrac{5}{8}

Therefore, the correct option is 4.
