Answer:

w = -9

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*w-(-27)=0

Step by step solution :

Step 1: Pulling out like terms

 Pull out like factors :

  3w + 27  =   3 • (w + 9)  

Equation at the end of step 1:

Step 2:

Equations which are never true:

Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

Solve  :    w+9 = 0  

Subtract  9  from both sides of the equation :  

                     w = -9

One solution was found :

w = -9

W=-9

Explanation: 3w=-27

Divide 3 from -27

-27 divided by 3 = -9

A shooting star forms a right triangle with the Earth and the Sun, as shown below:
Semmy [17]

I found this!!!!

The scientist can use these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.

- The scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=

hypotenuse

adjacent

and solve for the distance between the Sun and the shooting star (which would be the hypotenuse of the righ triangle).

Step-by-step explanation:

You can observe in the figure attached that "AC" is the distance between the Sun and the shooting star.

Knowing the distance between the Earth and the Sun "y" and the angle x°, the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.

This is:

cos\alpha=\frac{adjacent}{hypotenuse}cosα=

hypotenuse

adjacent

In this case:

\begin{gathered}\alpha=x\°\\\\adjacent=BC=y\\\\hypotenuse=AC\end{gathered}

α=x\°

adjacent=BC=y

hypotenuse=AC

Therefore, the scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=

hypotenuse

adjacent

, and solve for the distance between the Sun and the shooting star "AC":

cos(x\°)=\frac{y}{AC}cos(x\°)=

AC

y

AC=\frac{y}{cos(x\°)}AC=

cos(x\°)

y

Answer:

m\angle y=35.69^o

Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle of the figure

sin(y)=\frac{7}{12} ----> by SOH (opposite side divided by the hypotenuse)

using a calculator

m\angle y=sin^{-1}(\frac{7}{12})=35.69^o

Answer:

Slope is -2/7

Step-by-step explanation:

Slope formula is y₂-y₁/x₂-x₁

So...

(x₁,y₁) and (x₂,x₂) →(2,2) and (-5,4)

4-2= 2

-5-2= -7

2/-7
