Ineed to graph the points ! and i know you saw this

=====================================

Explanation:

Start at "2" on the number line. If you move to the right 6 steps, each time landing on a tickmark, then you'll arrive at "3" on the number line. This means the interval from 2 to 3 is cut into 6 equal pieces.

In other words, the little tickmarks represent 1/6 of a unit

If we go back to "2" on the number line, and move to the first tickmark, then we arrive at 2 & 1/6. Then the next tickmark would be 2 & 2/6, and so on.

Note how 2/6 = 1/3

So the mixed number 2 & 2/6 = 2 & 1/3

The location of 2 & 1/3 is marked in red in the diagram below.

--------------------------------

The mixed number 1 & 5/6 will be plotted a similar way.

Start at "1" on the number line. Count out 5 spaces until you arrive at 1 & 5/6. This is marked in blue in the same diagram. A shorter way is to start at "2" and count backward 1 tickmark. This works because the "2" is really 1 & 6/6. Going backward one tickmark has that "6/6" bump down to "5/6".

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
