The equation of line k is y=
Nina [5.8K]

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

I'm assuming you meant line k is y = 3x -2. If not, this is wrong.

For this, you need to put both lines in point-slope form, or the form that line k is already in. This means you only need to convert line m.

-2r + 6v = 18

6v = 2r + 18

v = 2/6r + 18/6

v = 1/3r + 3

Now you can answer the question.

To be parallel, lines must have the same slope (but a different y-intercept). 3 and 1/3 are not the same, so the lines are not parallel.

To be perpendicular, one line must have the opposite reciprocal (fraction flipped and + goes to - or - to +) of the other. While 3 is the reciprocal of 1/3, they are both positive, so they are not perpendicular.

To be the same line, the equations must be absolutely identical, which they aren't.

This leaves the last option: neither.

Let me know if you need a more in-depth explanation of anything here! I'm happy to help!

Answer:

In the given expression  x:6 ::  3:9 , x  = 2

Step-by-step explanation:

Here, the given expression is:

x:6 ::  3:9

or, x : 6 = 3 :9

So, by the RATIO OF PROPORTIONALITY:

\frac{x}{6} = \frac{3}{9}\\\implies x = \frac{3}{9} \times  6 = 2

or, x = 2

Hence, in the given expression  x:6 ::  3:9 , x  = 2
