-4(5k-7)-2k=-2(9k+5)

If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2

A line that includes the points (- 3, - 10) and (- 4,v) has a slope of - 4. What is the value of v?
tekilochka [14]

Answer:

The value of v with given slop and points is - 6

Step-by-step explanation:

Given as :

Let x and y be the points of a line

So, x = ( - 3 , - 10 )    And  y = ( - 4 , v )

The given slop of line XY is - 4

Now, from slop equation :

Slop = \frac{(y2 - y1)}{(x2 - x1)}

Or, - 4 = \frac{(v + 10)}{(- 4 + 3)}

Or, - 4 =  \frac{(v + 10)}{(- 1)}

Or, v + 10 = ( -4 ) × (- 1 )

Or, v + 10 = 4

∴    v = 4 - 10 = - 6

Hence The value of v with given slop and points is - 6      Answer
