Which two lines are parallel?

Mathematics
1 answer:
Masteriza [31]3 years ago
6 0

Answer:

  • 3x + y = -2
  • 2y = -6x – 8

Step-by-step explanation:

When the equations are written in the same form, the ratio of x coefficient to y coefficient is the same for parallel lines.

These equations in the same form are ...

  • 3x +y = -2
  • -6x +2y = 4
  • 6x +2y = -8

The first and last of these equations have a ratio of x-coefficient to y-coefficient of ...

  (x-coefficient)/(y-coefficient) = 3/1 = 6/2

so the lines are parallel.

The second equation has a ratio that is the opposite of this.

__

<em>Alternate approach</em>

You can put each equation into slope-intercept form (solve for y). The x-coefficient is then the slope of the line. Parallel lines** have equal slopes.

  • y = -3x -2 **
  • y = 3x +2
  • y = -3x -4 **

_____

I find a graphing calculator to be a big help for many problems involving equations and their characteristics.

andrew11 [14]

Answer:

(50+40x) dollars

Step-by-step explanation:

THe fixed cost is $50 (this includes everything and 6GB of data).

Now, for every GB <em>OVER</em> 6 GB he uses, company charges $40 extra.

So, if he used "x" GB EXTRA, his EXTRA cost will be 40 * x = 40x

Thus, his total cost in the month would be fixed cost PLUS the extra, which would be

50 + 40x dollars
