-2x-18= -4x=6

First, add 4x on both sides

-2x - 18= -4x-6

+ 4x      + 4x

2x-18=-6

Second, add 18 on both sides

2x-18= -6

  +18  +18

2x=12

Last, divide 2 on both sides

2x/2=12/2

x=6

Answer:

\boxed {x = 6}

Step-by-step explanation:

Solve for the value of x:

-2x - 18 = -4x - 6

-Take 4x and add it to -2x:

-2x - 18 + 4x = -4x + 4x  - 6

2x - 18 = -6

-Add both sides by 18:

2x - 18 + 18 = -6 + 18

2x = 12

-Divide both sides by 2:

\frac{2x}{2} = \frac{12}{2}

\boxed {x = 6}

Thus, the value of x is 6.

To determine whether the inverse of a function is a function, you can perform the vertical line test. A. True B. False
Andreas93 [3]
I think it's A since u would normal use the vertical line test on a line on a graph to see if it's a function.

Find the value of x and the value of y. 60 30 6
allochka39001 [22]

Answer:

  • The longest side, which is the opposite side of a right angle is the hypotenuse ( h ).

  • The opposite is the side opposite the angle involved and it is called the Perpendicular ( p ) .

  • The adjacent is the side next to the angle involved ( but not the hypotenuse ) and it is called the base ( b )

\large{ \tt{❃ \: TAKING  \: \angle \: \: A \: AS \: A \: ANGLE \: OF \: REFERENCE :  }}

  • Here , Perpendicular ( p ) = 6 , hypotenuse = y and now we're going to find the value of y first : We know :

\large{ \tt{❁ \: sin \:  60 \degree =  \frac{perpendicular}{hypotenuse} }}

\large{ \tt{➝ \:  \frac{ \sqrt{3} }{2} =  \frac{6}{y}  }}

\large{ \tt{➝ \sqrt{3}y = 6 \times 2 }}

\large{ \tt{➝ \:  \sqrt{3} \: y = 12 }}

\large{ \tt{➝ \: y=  \frac{12}{ \sqrt{ 3} } }}

\boxed{ \large{ \tt{➝ y = \: 4 \sqrt{3} }}}

\large{ \tt{❇ \: TAKING  \: \angle \: B \: AS \: THE \: ANGLE \: OF \: REFERENCE}} :

  • Here - Perpendicular ( p ) = x , hypotenuse = y = 4 √ 3 and Now , we're gonna find the value of x :

\large{ \tt{❊ \: sin  \: 30 \degree =  \frac{perpendicular}{hypotenuse} }}

\large{ \tt{⟶ \:  \frac{1}{2} =  \frac{x}{4 \sqrt{3} }  }}

\large{ \tt{⟶ \: 2x = 4 \sqrt{3} }}

\large{ \tt{⟶ \: x =  \frac{4 \sqrt{3} }{2} }}

\boxed{\large{ \tt{⟶ \: x = 2 \sqrt{3} }}}

\boxed{  \large{ \tt{❈ \:  OUR \: FINAL \: ANSWER :  \boxed{ \tt \: x = 2 \sqrt{3}   \: \: y = 4 \sqrt{3} }✓}}}

  • And we're done! Hope I helped! Let me know if you have any questions regarding my answer and also notify me , if you need any other help ! :)
