Solve each system of equations. Determine which quadrant the solution lies in.

ITEM BANK: Move to Bottom
2x - y = -2
x - 2y = 53x + 2y = 10
5x - 2y = 63x + y = 3
2x + 4y = 225x - 2y = -19
3x + y = -7x - y = -3
x + y = -7y = -2x
3x - y = 10y = 2x - 9
y = x - 5y = x - 2
2x - 3y = -5

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.

2/3(-6y+9x) expand each expression using the distributive property
