F(x) and g(x) are polynomial functions. Determine whether each expression is always, sometimes, or never a polynomial.

f(x)+g(x)
and
f(x) / g(x)

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
