Answer:

B,-7

Step-by-step explanation:

convert the formualt into slope intercept form by adding the 3 and distributing the -2

then you will get y=-2x-7

in slope intercept the B slot is the y intercept, and in this equation it is -7

we know that

A rectangle is a quadrilateral with four right angles and two pairs of congruent and parallel sides

see the attached figure to better understand the problem

$m$

$AB=CD$

$BC=AD$

therefore

Cos 4θ − cos 2θ = sin θ

hichkok12 [17]

$cos(4\theta) - cos(2\theta) = sin(\theta)$
$-2sin(\frac{4\theta + 2\theta}{2})sin(\frac{4\theta - 2\theta}{2}) = sin(\theta)$
$-2sin(\frac{6\theta}{2}sin\frac{2\theta}{2}) = sin(\theta)$
$-2sin(3\theta)sin(\theta) = sin(\theta)$
$\frac{-2sin(3\theta)sin(\theta)}{-2sin(\theta)} = \frac{sin(\theta)}{-2sin(\theta)}$
$sin(3\theta) = -\frac{1}{2}$
$sin^{-1}[sin(3\theta)] = sin^{-1}(-\frac{1}{2})$
$3\theta = -30$
$\frac{3\theta}{3} = \frac{-30}{3}$
$\theta = -10$
