Darlene purchases 20,000 worth of stock on her brokers advice and pays her broker a 1.5% broker fee darlene purchases 20,000 worth of stock on your brokers advice and pays her broker a 1.5% broker freeshe sells her stock when it increases to $28,600.02 years later and uses a discount broker who charges $21 per trade compute Darlenes net proceeds after the broker fees are taken out

Answers

Answer:

Darlene's net proceeds after the broker fees are taken out is $8,279.

Step-by-step explanation:

From the question, the following can be obtained:

Basic cost of purchase of the stock = $20,000

Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300

Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300

Selling price = $28,600

Broker fees related sales = 21

The net proceed can therefore be calculated as follows:

Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock  = $28,600 - $21 - $20,300 = $8,279

Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.

54x + 15 = -3 (3y + 1)
I need help finding the equation for y

Answers

Answer: y = -6x - 2  

Step-by-step explanation:

54x + 15 = -3(3y + 1)   To solve for y distribute on the right side to get,

54x + 15 = -9y -3        Add 3 to both sides

      +3             +3

54x  + 18 = -9y        Divide each term by -9 on each side.

y = -6x - 2

Answer______

54x + 15 = -3 (3y + 1)

54x + 15 = -9y -3

+3 +3

54x + 18 = -9y

y = -6x - 2

The discriminant is -23

The equation has 0 real solution

Step-by-step explanation:

The discriminant of the quadratic equation ax² + b x + c = 0 is Δ = b² - 4ac

If Δ > 0, then the equation has two different real solutionsIf Δ = 0, then the equation has one real solutionIf Δ < 0, then the equation has no real solutions

Let us use the rule above to solve the question

∵ x² - x + 6 = 0

∴ a = 1, b = -1 and c = 6

∵ Δ = b² - 4ac

∴ Δ = (-1)² - 4(1)(6)

∴ Δ = 1 - 24

∴ Δ = -23

∴ The discriminant is -23

∵ -23 < 0

∴ Δ < 0

∴ The equation has no real solutions

∴ The equation has 0 real solution

What is an equation of the line that passes through the points (-3, -1)(and (-4, -4)? Put your answer in fully reduced form.

Answers

Answer:

y=3x+8

Step-by-step explanation:

m=3

y-(-1)=3(x-(-3))

y+1=3x+9

y=3x+8

The equation of the line passes through the point  (-3, -1)(and (-4, -4) is y=3x+8.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line passes through the points (-3, -1)(and (-4, -4)

The slope will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -4 + 1 ) / ( -4 + 3 )

Slope = 3

The y-intercept is calculated as,

y = 3x + c

-1 = 3 x -3 + c

c = 8

The equation of the line will be,

y=3x+8
