<h2>Answer:</h2>
A function from a set
to a set
is a relation that assigns to each element
in the set
exactly one element
in the set
. The set
is the domain (also called the set of inputs) of the function and the set
contains the range (also called the set of outputs).
- First figure is not a function because the x-coordinate 2 has more than one element in the set of outputs.
- Second figure is a function because this each element
in the set
is assigned to exactly one element
in the set
.
- Third figure is not a function because the x-coordinates -1, 1 and 2 have assigned more than one element in the set of outputs.
- Fourth figure is a function because this each element
Answer:
The answer in the procedure
Step-by-step explanation:
Let
x ----> the dog walking hours
y ----> the car washing hours
we know that
The system of linear inequalities is equal to
-----> inequality A
-----> inequality B
Solve the system of inequalities by graphing
The solution is the shaded area
see the attached figure
Two possible combinations of hours are
(10,10) and (0,9)
<em>Verify</em>
For (10,10)
Substitute the value of x and the value of y in both inequalities
<em>Inequality A</em>
-----> is true
<em>Inequality B</em>
----> is true
therefore
(10,10) is a possible solution
For (0.9)
Substitute the value of x and the value of y in both inequalities
<em>Inequality A</em>
-----> is true
<em>Inequality B</em>
----> is true
therefore
(0,9) is a possible solution
