Here are two equations that relate two quantities, p and Q:
Q=7p+1,999
p=\frac{Q-1,999}{7}
Select all statements that are true about p and Q.

Q= 7p +1,999 could represent a function, but p=\frac{Q-1,999}{7} could not.

Each equation could represent a function.

p=\frac{Q-1,999}{7} could represent a function, but Q= 7p +1,999 could not.

The two equations represent two functions that are inverses of one another.

If Q= 7p +1,999 represents a function, then the inverse function can be defined by p=\frac{Q-1,999}{7}.
