Answer:

x = 3

Step-by-step explanation:

calculate the slope using the slope formula and equate the result to - 2

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (x, 8)

m = \frac{8-4}{x-5} = \frac{4}{x-5} = - 2, thus

- 2(x - 5) = 4, that is

- 2x + 10 = 4 ( subtract 10 from both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3

erica [24]
Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
                                                             = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
                                                             = 10 * 63 dollars
                                                             = 630 dollars
Rate at which each stocks were sold = 35 1/4
                                                             = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
                                                         = 5 * 141 dollars
                                                         = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
                                                                      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".

docker41 [41]

Answer:

Given the equation of line :  3x -2y = -18

Table values:

x                  y

0                  9

2                  12

4                   15

6                   18

-6                  0

Now, plot these points (0,9), (2, 12), (4, 15) , (6, 18) and (-6, 0) on the co-ordinate planer, to graph the the line.

You can see the graph of the given equation as shown below.
