Solve for x: 3(x + 1) = −2(x − 1) − 4

1 answer:

4 0

Solve your equation step-by-step.

3(x+1)=−2(x−1)−4

Simplify both sides of the equation.

3(x+1)=−2(x−1)−4

Simplify:

3x+3=−2x−2

Add 2x to both sides.

3x+3+2x=−2x−2+2x

5x+3=−2

Subtract 3 from both sides.

5x+3−3=−2−3

5x=−5

Divide both sides by 5.

5x/5 = −5/5

x=−1

Given circle and circle with radii of 6cm and 4cm respectively.

noname [10]

Solution :

Given that :

The radius of circle A = 6 cm

The radius of circle C = 4 cm

In circle A

$\angle EAF = \theta = 140^\circ$

The length of arc EF = $2 \pi r \times \frac{\theta}{360^\circ}$

$=2 \times 3.14 \times 6 \times \frac{140^\circ}{360^\circ}$

= 14.653 cm

In circle C

$\angle GCH = \theta = 140^\circ$

The length of arc GH = $2 \pi r \times \frac{\theta}{360^\circ}$

$=2 \times 3.14 \times 4 \times \frac{140^\circ}{360^\circ}$

= 9.769 cm

Therefore,

The length of EF is 14.653 cm

The length of GH is 9.769 cm

The length of EF is 1.5 times the length of GH

i.e. 14.653 = 1.5 x 9.769

14.653 = 14.653

Hence proved.

Function g is a transformation of the parent sine function such that g(x) = sin(x - pi) - 2. which graph represents function g?

azamat

Answer:

The lower left image is best

Step-by-step explanation:

Sine 0 or -π are both zero, but increasing x would normally have the line moving above the neutral line. Subtracting π from the x value inverts the sine wave so the line moves first below the neutral line as x increases.

Subtracting 2 from all sine results shifts the neutral line down 2 units.
