How many terms does the expression 2x+3y+1 have?

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.

3x + 4y = 5 x- 3y = -7 solve by substitution

Suppose the equation ||x-a|-b|=2008 has 3 distinct real roots and a not =0. find the value of b.
