Answer:
8 salt water
7 fresh water
Step-by-step explanation:
Let's represent salt water fish with the variable "s" and fresh water fish with the variable "f".
We can make a system of equations - one equation for the number of fish and the other for the price of the fish.
We know that the total number of fish Laura has is 15, and the total price of the fish was $23.
Solve the system of equations by subtracting the bottom equation from the top equation.
Laura bought 8 salt water fish. Since the total number of fish is 15, the number of fresh water fish must be 7.

The domain and range for the following given graph or relation will be [-7,8] and [-4,3] respectively.
As per the question statement, we are given a graph which is depicted as a relation and we are supposed to tell the domain and range of the particular relation.
Now, before solving it, we need to know that domain refers to the set of possible input values and it consists of all the input values shown on the x-axis and range is the set of possible output values which are shown on the y-axis.
So, Domain : [-7,8]
And Range : [-4,3]
Hence, the domain and range for the following given graph or relation will be [-7,8] and [-4,3] respectively.
- Domain: It refers to the set of all the possible input values and basically it consists all the input values shown on x-axis.
- Range: It refers to the set of all the possible output values and basically it consists all the output values shown on y-axis.
