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 )

Finding the slope

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. O A. x = +3,5 B. x = +39 O C. x = +9.12 D. X = +9.5

Eduardwww [97]

Answer:

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:

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