Pierre is running 26 and 2/10 miles in the marathon. he has ran 3/4 of the way. How far has he run?
vredina [299]
Distance=(3/4) * (26  2/10  miles)

26  2/10  miles=26  1/5 miles=(5*26+1) / 5 miles=131/5 miles.

Therefore:

distance=(3/4) * (26  2/10 miles)=(3/4) * (131 /5 miles)=
=(131 *3) / (4*5) miles=393/20 miles= (19*20+13)20 miles=19  13/20 miles.


he has run 393/20 miles    or    19  13/20  miles

Find the slope of the line passing through the points (-6-9) and (9,-9)
Otrada [13]

9514 1404 393

Answer:

  • zero
  • undefined

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

__

<u>First line</u>:

  m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0

The slope of the first line is zero.

__

<u>Second line</u>:

  m = (-5-1)/(4 -4) = -6/0 = undefined

The slope of the second line is undefined.

_____

It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.

Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.
