Answer:
The system cannot be solved by a unique cost for each soldier, because has infinite solutions
Step-by-step explanation:
Let
x-------> the cost of a legionary per day
y-------> the cost of an archer per day
we know that
------> equation A
------> equation B
Multiply equation B by both sides
------->
so
equation A and equation B is the same equation
therefore
This is a consistent dependent system
The system has infinite solutions
Answer:
The graph is shown below.
Step-by-step explanation:
The given piecewise function is
From the given piecewise function, it is clear that
for x<0.
Put different values of x in f(x) where x<0 and find the values of f(x) to make a table of values as shown below.
Table of values:
x f(x)
-3 3
-2 2
-1 1
Now, plot the points (-4,4),(-3,3),(-2,2),(-1,1) and join them by straight line. There is an open circle at x=0 because 0 is not included in this function.
From the given piecewise function, it is clear that
for
.
Table of values:
x f(x)
0 0
1 1
2 4
Plot the points (0,0), (1,1), (2,4) and join them by a curve. There is closed circle at 0 because 0 is included in this function.
The graph is shown below.
