The supplements of each angle are complementary:

  (180 -6x) +(180 -4x) = 90 . . . . . . . . assumes x is in degrees

  270 = 10x . . . . . . add 10x-90

PLEASE PLEASE HELP!!!!
Usimov [2.4K]

Answer:

B

Step-by-step explanation:

\cos( \alpha )  +  i\sin( \alpha )  =  {e}^{i (\alpha   + 2\pi)}

z = 3(cos π/2 + i sin π/2) =→

3 {e}^{i \frac{\pi}{2} }

z⁷ =

{3}^{7}  {e}^{i \frac{7\pi}{2} }  =   {3}^{7}  {e}^{i \frac{(7 - 4)\pi}{2} }  =  {3}^{7}  {e}^{i \frac{3\pi}{2} }  =  {3}^{7} ( \cos( \frac{3\pi}{2} )  + i \sin( \frac{3\pi}{2} ) ) = 2187( \cos( \frac{3\pi}{2} )  + i \sin( \frac{3\pi}{2} ) )

What is the equation of the line that passes through the points (−2, 1) and (1, 10)?
Viktor [21]

Answer:

3x - y = -7

Step-by-step explanation:

y = mx + b

m = deltay/deltax

m = (10 - 1)/[( 1 - (-2)]

m = 9/3 = 3

y = 3x + b

From (-2 | 1) we see that when x = -2, y = 1

Placing into the equation, in order to find b (y-intercept)

y = 3x + b

1 = 3(-2) + b

b = 7

y = 3x + 7 or 3x - y = -7
