5/6x - x/3 + 1 = 8/9.....multiply by LCD of 18
15x - 6 + 18 = 16...voila, no fractions

miss Akunina [59]

The quadrilateral which can be considered  as a "Parallelogram" or "Not necessarily a parallelogram. are second and fourth figure.

"The correct figures are (b) and (d)

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal).

  • The first one is a parallelogram because, the angle are shown are alternate interior angles which defined between two parallel lines.

  • The second one is not a parallelogram because, the angle are shown are alternate interior angles which should defined between two parallel lines. But there are no parallel lines.

  • The third one is not a parallelogram because, the parallelogram have opposite angles are equals not the adjacent angle.

        Here the adjacent angle are given equal.

  • The fourth one is a parallelogram because, the opposite side of parallelogram are equal and parallel to each other.

hich function is the same as y = 3 cosine (2 (x + StartFraction pi Over 2 EndFraction)) minus 2? y = 3 sine (2 (x + StartFractio
Assoli18 [71]

Answer:

B) y = -3 sin(2(x + π/4)) - 2

Step-by-step explanation:

Which function is the same as y = 3 cos(2 (x + π/2)) - 2

A)  y = 3 sin(2(x + π/2)) - 2

B) y = -3 sin(2(x + π/4)) - 2

C) y = 3 cos(2 (x + π/4)) - 2

D) y = -3 cos(2 (x + π/2)) - 2

y = 3 cos(2 (x + π/2)) - 2

Sine and cosine have the following relationship:

cos(θ) = sin (π/2 - θ)

y = 3 cos(2 (x + π/2)) - 2

⇒ y = 3 cos(2x + π) - 2

Let θ = 2x + π, therefore using Sine and cosine have the following relationship:

cos(2x + π) = sin (π/2- (2x + π))

= sin (π/2 - 2x - π)

= sin (-2x - π/2)

= sin (-2(x + π/4))

but sin(-θ) = -sin (θ)

Therefore:

sin (-2(x + π/4)) = -sin (2(x + π/4))

⇒ - sin (2(x + π/4)) = cos(2x + π)

y = 3 cos(2x + π) - 2 = 3[ - sin (2(x + π/4))] -2

y = -3 sin (2(x + π/4)) -2
