Answer:

x = ± 4

Step-by-step explanation:

Given

3 | x | + 2 = 14 ( subtract 2 from both sides )

3 | x | = 12 ( divide both sides by 3 )

| x | = 4

x = ± 4

Since | - 4 | = | 4 | = 4

Kathy sells candles for $3 and flowers for $5. She plans to sell at least 200 items and likes to earn a minimum of $2500.

Answer:

$\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right$

Step-by-step explanation:

System of equations

Kathy sells candles for $3 and flowers for $5. Let's set the following variables:

x = number of candles Kathy sells

y = number of flowers Kathy sells

She plans to sell 200 items, thus:

x + y = 200

She also likes to earn $2,500. The equation for this condition is:

3x + 5y = 2500

The system of equations is

$\left\{\begin{matrix}x + y = 200\\ 3x + 5y = 2500\end{matrix}\right$

Sharon purchased a used car for $24,600. The car depreciates exponentially by 8% per

Tju [1.3M]

Answer:

The value of car after 5 years of exponentially depreciation is $16,213.36

Step-by-step explanation:

The initial amount of the car = i = $24,600

The depreciates rate of interest applied = r = 8%

Let The value of car after n years = A

The number of years = n = 5 years

Now,According to question

The value of car after n years = initial price of car × $(1-\dfrac{\textrm rate}{100})^{\textrm time}$

Or, The value of car after 5 years = i × $(1-\dfrac{\textrm r}{100})^{\textrm n}$

Or, $A = $24,600 × $(1-\dfrac{\textrm 8}{100})^{\textrm 5}$

Or, $A = $24,600 × $(0.92)^{5}$

Or, $A = $24,600 × 0.65908

Or, $A = $16,213.36

So, The value of car after 5 years = A = $16,213.36

Hence , The value of car after 5 years of exponentially depreciation is $16,213.36 . Answer

we are given

BE=x

ED=x+10

AE=x+1

EC=x+3

we can see that two chords AC and BD are intersecting inside the circle

so, we can use property

$AE*EC=BE*ED$

now, we can plug values

$(x+1)*(x+3)=(x)*(x+10)$

now, we can multiply them

$x^2+4x+3=x^2+10x$

now, we can move all terms on left side

$x^2+4x+3-x^2-10x=0$

$3-6x=0$
