How do i solve 3x+3y=-3 and y=5x-1 each system by substitution?

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.

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
