At raging river sports, polyester fill sleeping bags sell for $79. Down fill sleeping bags sell for $149. In one week the store
1 answer:
9 Polyester fill and 5 down fill sleeping bags were sold.
Step-by-step explanation:
Let,
Polyester fill sleeping bags = x
Down fill sleeping bags = y
Price of 1 polyester fill bag = $79
Price of 1 down fill bag = $149
According to given statement;
x+y=14 Eqn 1
79x+149y=1456 Eqn 2
Multiplying Eqn 1 by 79
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 70
Putting y=5 in Eqn 1
9 Polyester fill and 5 down fill sleeping bags were sold.

We know the following relationship:
The domain of a function are the inputs of the function, that is, a function
is a relation that assigns to each element 
in the set A exactly one element in the set B. The set A is the domain (or set of inputs) of the function and the set B contains the range (or set of outputs).Then applying this concept to our function 
we can write its domain as follows:
