Answer:

x = 5/3 x = -1

Step-by-step explanation:

|3x-1| = 4

There are two solutions, one positive and one negative

3x-1 =4 and 3x-1 = -4

Add 1 to each side

3x-1+1 = 4+1 3x-1+1 = -4+1

3x = 5 3x = -3

Divide by 3

3x/3 = 5/3 3x/3 = -3/3

x = 5/3 x = -1

Prove this trigonometric identity sin 3x/sin x - cos 3x/cos x =2

Sveta_85 [38]

Step-by-step explanation:

LHS= sin 3x/sin x - cos 3x/cosx

Taking LCM,

=sin3xcosx- cos3xsinx

sinxcosx

=sin(3x-x)

sinxcosx

= 2sin2x

2sinxcosx

= 2sin2x

sin2x

= RHS.

Proved.

Find the values of x and y

vitfil [10]

Hi there!

$\large\boxed{y = 12, x = 3}$

The two trapezoids are similar, so we can determine a common scale factor:

OL/UR = NM/TS

9/3 = 6/2

3 = 3

Trapezoid ONML is 3x larger than UTSR, so:

RS = 4, LM = y

3RS = LM

3 · 4 = y = 12.

Find x using the same method:

3UT = ON

3(2x+1) = 4x + 9

6x + 3 = 4x + 9

2x = 6

x = 3.
