to be a function, each input can have only one output. For these points, each x has only one y, so it it a function. A relation, just describes x to y, so it is both
Answer:
It is a little bit trivial:
As we know:
Energy sink: is anything that uses energy.
Energy source: is anything that produces energy.
How the caol deposits can be energy sinks? well, you want to extract the coal from those deposits, and to do it, you need to "use energy" (the type of energy can depend on the extraction method, for example, if you use a pickaxe to extract the coal, you are using mechanical energy)
These coals are potential energy sources because coal is an energy source, potential means that, given some circumstances, something can transform into other things.
So potential energy source in this situation means that those coal deposits can be potential energy when we extract the coal and use it as an energy source.
Answer: C. Distribute 3/4 over (x-8)
Step-by-step explanation:
To solve any(technically most, but still...) algebraic equation you must isolate the variable. In this case, the first step would either be to divide both sides of the equation by 3/4, or distribute 3/4 to x and -8, as you cannot modify the contents of the parenthesis without removing the 3/4.
Hope it helps and lmk if you further explanation <3 :)
