So,

1. Graph each inequality separately.
2. Choose a test point to determine which side of the line needs to be shaded.
3. The solution to the system will be the area where the shadings from each inequality overlap one another (purple area)
As for the system of inequalities we say it's unbounded.
Answer:
The feasible region in the attached figure
Step-by-step explanation:
Let
x ----> the number of shirts
y ----> the number of pants
we know that
The cost of the shirts (number of shirts multiplied by the cost of one shirt) plus the cost of the pants (number of pants multiplied by the cost of one pant) must be less than or equal to $80
so
The inequality that represent this problem is

using a graphing tool
The feasible region is the triangular shaded area
see the attached figure
Answer:
no it is not
Step-by-step explanation:
it would be 54
Answer:
Exponential decay.
Step-by-step explanation:
The magnitude of the base (also known as the "common factor") tells us whether a given exponential equation represents growth or decay.
Standard equation for expo. growth: y = 3(b)^x, where b is the base.
If 0<b<1, we have expo. decay; if 1<b, we have expo. growth.
Thus, y = 3(0.5)^x represents expo. decay.
Answer: $30
Step-by-step explanation: The formula for simple interest is principal x rate x time.
Putting your numbers into the formula, it will look like this:
I = 500 x .06 x 1
I = 30 x 1
I = 30
The interest on $500 for one year is $30.
