|-9| means the absolute value of -9 which is 9
so we have 9 - 9 = 0 (answer)
x+y=45 and x=y+15
Therefore, x is 30 and y is 15
x is greater than y by 15, and their sum in 45.
The larger number is 30 and the smaller number is 15.

Answer:
<em>A) (-5,7)</em>
Step-by-step explanation:
<u>Functions and Relations</u>
A set of values A can have a relation with another set B as long as at least one element of A has at least one image in B. Functions are special relations where each element of A (the domain of the function) has one and only one image on B (the range of the function).
By looking at the options, we can see that x=9, x=-8, and x=-1 already have defined values in Y, so if we define another value for any of them the relation will stop being a function. The only possible choice to preserve the function is the option

4.50×6=27.00. the total cost of the box will be $27.00
