esents A. dependent B. inconsistent C. consistent system the letter of the correct answer before each number. y +5 - 1/x + 5 2y = x + 10 1. = y=-3x-1 2. 3y = -9x - 3 3. X y = x +5 18x + y = -2 y = 3x-1 4. 3 8x + y = -1 5. y = x and x + 2y = 6 6. y = 3x and 2x - y = 6 7. y = 2x and 3x + 2y = 1 8. 3x + 5y + 20 and 12x + 20x + 80
If a system has atleast ond solution,it is said to br consistent
if a consistentsystem has exactly one solution,it is independent
when you graph the equations,the line of the two equationintersect each other
if a consistent system hasan infinite numbers of solutions,its is dependent.When you graph the question. both equations represent thr some line
If a system has no solution,it is said to be inconsistent.the graphs of the lines do not intersect. so the graphs are parallel and there is no solution.
