Answer:
Step-by-step explanation:
1. Relation - a set of ordered pairs
2. Vertical line test - a test used to determine if a graph is a function; states that a vertical line can only go through one point on the graph to be a function
3. Function - a relation in which for any given input value, there is only one output value
4. Output - value generated by a function when an input value is substituted into the function and evaluated
5. Ordered pair - a group of two numbers written in the form (x, y) where the x value represents a horizontal position and the y value represents a vertical position
6. Mapping Diagram - a table or diagram that represents a mathematical relation
7. Input - a value that is substituted in for the variable in a function in order to generate an output value
I hated doing that stuff, it was a pain for me
Each of Tony’s items are $7.65
Each of Tanyas items are $10.2
Well, the answer is 12. This is because you need to add the inverse operation. So for (6x-6) You add 6 or the second number( the one that doesn't have the x in front of it)because it is the opposite/inverse operation.You basically just add 6 and because the opposite of subtraction is addition. You then cross is out because it will equal zero. Then with the 6x, you add 6 as well because what you do to one side, you must do the same to the other. so 6+6=12. SO x=12.
