Answer:
1764 ways
Step-by-step explanation:
Number of ways of selecting 6 cows from 9 cows and 5 buffaloes from 7
Using the combination formula:
nCr = n! ÷ (n - r)! r!
Ciw selection:
9C6 = 9! ÷ (9-6)! 6!
9C6 = 84
Buffalo Selection:
7C5 = 7! ÷ (7-5)! 5!
7C5 = 21
9C6 * 7C5
84 * 21
= 1764 ways

Answer: (-7, 4)</h3>
Other solutions are possible.
=====================================================
Explanation:
The dashed line is
. We shade above this dashed line to draw the region for
. This region is shown in green and also the gray region as well.
The purple and gray region is
which consists of the solid boundary line
and stuff below it.
When considering both inequalities at the same time, we shade above the dashed line and below the solid line to get the gray region only.
This gray region is the solution set of the system of inequalities. Pick any point from this region to get the final answer.
One such point is (-7, 4). There are infinitely many other possible answers.
To verify that point, plug in the coordinates into each inequality. When simplifying, you should get a true statement.
If one inch is 60 then 3 would be 60*3 which is 180. The .5 s half of one so the half of 60 is 30. Add that to 180 and 180+30=210.
The answer is 210 miles
