Answer:
Step-by-step explanation:
We are given that an expression models the final price of television set with an instant rebate in a state that charges a sales tax.
The sale tax in on the original price .
We have to find an expression that represents the price of the television set after the instant rebate is applied but before the tax is applied.
Let x be the original price of television.
Instant rebate is subtracted from original price x.
Then , the cost of the television set=x-300
In the given expression 0.07 x is sales tax. where tax is 7 % on the original price x.
Sales tax is added to the price of television set.
Hence, option C is true.
Answer:
The domain is the set of x values that has a corresponding y-values in a function or a graph.
The domain of the graph is:
From the graph (see attachment), we have the following observation
These values can be represented as:
So, the domain of x is:
