For what value of x must ABCD be a parallelogram?<br><br> Picture below*
sesenic [268]

Answer:

x = 5

Step-by-step explanation:

Comment

BD is already given to you as bisected. AC must also be bisected. That means that 6x and 7x - 5 must the the same value. Then and only then will the figure be a parallelogram. (a four sided figure is a parallelogram if the 2 diagonals are bisected.

Equation

6x = 7x - 5                    Subtract 6x from both sides

Solution

6x - 6x = 7x - 6x - 5     Simplify

0 = x - 5                        Add 5 to both sides

5 = x - 5 + 5                 Simplify

x = 5

A company just paid a dividend of $1.20 per share at the end of the year. It is expected to grow at 12% per year for three years
grigory [225]

The current price of the stock given the dividend, cost of equity and growth rates is $46.90.

<h3>What is the current stock price?</h3>

Thw two-stage dividend growth model would be used to determine the value of the stock.

First stage:

  • dividend in Y1 = 1.20x 1.12 = 1.344
  • dividend in Y2 = 1.20 x 1.12^2 = 1.505
  • dividend in Y3 = 1.20 x 1.12^3 = 1.69

Second stage:

Y3 = (1.69 X 1.06) / (0.095 - 0.06) = 51.059

Find the present value of these cash flows

(1.344 / 1.095) + (1.505 / 1.095²) + (1.69 / 1.095³) + (51.059/1.095³) = $46.90

What is the slop-intercept of the line that passes through the points (7,-5) and (3,-9)?
bagirrra123 [75]

\bf (\stackrel{x_1}{7}~,~\stackrel{y_1}{-5})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-9}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-9-(-5)}{3-7}\implies \cfrac{-9+5}{-4}\implies \cfrac{-4}{-4}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-5)=1(x-7) \\\\\\ y+5=x-7\implies y=x-12
