(7,-1) and ( 21,-5) what is the slope
mart [117]

Answer:

-2/7

Step-by-step explanation:

Going from (7,-1) to ( 21,-5) we see x (the 'run') increasing by 14 and y (the 'rise') decreasing by 4.  Thus, the slope of the line connecting these two points is m = rise/run = -4/14, or -2/7.

There are 3 people in a room, and we are curious whether two of them have their birthday in the same month. We record the triple
xxMikexx [17]

Answer:

The possible outcomes are 1728.

Step-by-step explanation:

Consider the provided information.

We know that there are 12 months in a year and we have 3 people in a room.

As the order is important it means for each person we have 12 choices of the months.

The possible outcomes are: 12\times12\times12=1728

Hence, the possible outcomes are 1728.

A marvellous spatuletail is flying at an elevation of 4294 \dfrac29492​4, start fraction, 2, divided by, 9, end fraction meters.
user100 [1]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as what is required is not stated.

<em>However, since it deals with height of different elevations and these heights are represented by fractions, a possible question could be to calculate the difference between both elevations </em>

Represent Marvellous Spatuletail with M and Asian crested ibis with A.

M = 4\frac{2}{9}

A = 10\frac{1}{4}

Calculating the difference (D).

To do this, we make use of absolute difference as follows:

D = |M - A|

Substitute values for M and A

D = |4\frac{2}{9} - 10\frac{1}{4}|

Convert fraction to improper numbers.

D = |\frac{38}{9} - \frac{41}{4}|

Take LCM

D = |\frac{38*4-41*9}{36}|

D = |\frac{152-369}{36}|

D = |\frac{-217}{36}|

Remove the absolute sign

D = \frac{217}{36}

D = 6\frac{1}{36}

<em>Hence, the difference between both elevations is: </em>6\frac{1}{36}\ meters<em></em>

Another possible question is to determine which of the two is flying at a higher elevation or lower elevation

We have.

M = 4\frac{2}{9}

A = 10\frac{1}{4}

Compare the integer parts of both fractions.

10 > 4

So, A flies at a higher elevation.

<em>Hence: Asian crested ibis flies at a higher elevation and Marvellous Spatuletail flies at a lower elevation.</em>
