Answer:
m = 4
Step-by-step explanation:
Substitute x = 1, y = 1 , that is(1,1) into the equation
1 - 5 = m(1 - 2)
- 4 = - m ( multiply both sides by - 1 )
m = 4
5/16 inches, because if you look on a ruler, 5/16 inches is much longer
Answer:
Option b (4,1)
Step-by-step explanation:
The region given by the system of inequalities is shown in the graph. We must look within this region for the point that minimizes the objective function 
The minimum points are found in the lower vertices of the region.
These vertices are found by equating the equations of the lines::
-------------------
---------------------
The lower vertices are:
(4, 1) (2, 4)
Now we substitute both points in the objective function to see which of them we get the lowest value of 
Then the value that minimizes f(x, y) is (4,1).
Option b
Twelve men take 6 hours to finish a piece of work.
In 1 hour, the 12 men will finish 1/6 of the work
( 1 job ) / ( 6 hrs ) = ( 1/6 of a job ) / ( 1 hr )
-----------------------------------------
That means there is of the job
left to do.
-------------------
If 12 men take 6 hours to finish a piece of work,
1 man will take 12 times as long, to finish the work, so
( 1 job ) / ( 6*12 = 72 hrs ) = rate of working for 1 man, or
-------------------
After 1 hour, there are a total of men working
20 men will work 20 times as fast as 1 man on the
of a job that remains, so
Let = hours for the 20 men to finish the job
