X= 47.5 degrees... it has to equal 100 degrees
ziro4ka [17]3 years ago
6 0

Answer:

x = 47.5

Step-by-step explanation:

The vertical angle theorem states that if two angles are vertical, they are congruent, so the two angles you gave are congruent.

2x + 5 = 100

2x = 95

x = 47.5

Find the slope of (3,-3) and (0,3)
Vinil7 [7]

Answer:

<h3>\boxed{ \bold{ \huge{ \boxed{ \sf{ - 2}}}}}</h3>

Step-by-step explanation:

Let the points be A and B

A ( 3 , -3 ) ⇒( x₁ , y₁ )

B ( 0 , 3 )⇒ ( x₂ , y₂ )

<u>Finding</u><u> </u><u>the </u><u>slope</u>

Slope ( m ) = \sf{ \frac{y2 - y1}{x2 - x1} }

plug the values

⇒\sf{ \frac{3 - ( - 3)}{0 - 3} }

We know that , \sf{( - ) \times ( - ) = ( + )}

⇒\sf{ \frac{3 + 3}{0 - 3} }

Calculate

⇒\sf{ \frac{6}{ - 3} }

⇒\sf{ - 2}

Hope I helped!

Best regards!!

Find the solutions to x2 = 27.<br> O A. x = +3,5<br> B. x = +39<br> O C. x = +9.12<br> D. X = +9.5
Eduardwww [97]

Answer:

A

Step-by-step explanation:

Given

x² = 27 ( take the square root of both sides )

x = ± \sqrt{27}

  = ± \sqrt{9(3)}

  = ± \sqrt{9} × \sqrt{3}

  = ± 3\sqrt{3} → A

Solve the system of equations by graphing. x+y=-9 4x+y=-19
shutvik [7]

For this case we have the following system of equations:

x + y = -9\\4x + y = -19

We multiply the first equation by -4:

-4x-4y = 36

We have the following equivalent system of equations:

-4x-4y = 36\\4x + y = -19

We add the equations:

-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}

We find the value of the variable "x":

x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}

Thus, the solution of the system is:

(x, y): (- \frac {10} {3}, - \frac {17} {3})

See the graphic in the attached image

ANswer:

(x, y): (- \frac {10} {3}, - \frac {17} {3})
