the answer to your question is 13 mm
If it has only one solution that means that there is only one value of x that will fulfill this equation
35 - 5x + 6x - 36 = -24 - 17x + 17x + 24
-5x + 6x - 36 = -24 -17x + 17x + 24 - 35
x - 36 = -24 + 24 - 35 (I just canceled out the 17x because it would have justy made the process longer if I moved them over)
x = -24 + 24 - 35 + 36
x = -35 + 36
x = 1
Answer:
To solve this you would do the following:
We know her plan is $15/monthly, regardless of any additional texts/calls she makes.
If 1 minute = $.20 worth of money, we would simply multiply 30 (she made 30 minutes worth of calls) x $.20 ($.20 for each minute). The product is $6.
So, $15 + $6 = $21.
Unless the amount owed per text is mentioned and you forgot to include it in the title, you would not need to take this into consideration.
In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?
