1) 2x+4y=10
3x+5y=14 .
find d2, dx2, and dy
2) Solve the system of equations algebraically and show your work.
2x + 3y = 12
2x - y = 4
3) Which of the ordered pairs (5,5),(5,0) and (-3,2) can be found in the shaded solution area for the system of inequalities below? (The ordered pair must be in the double shaded region or it is not a solution of the system.)
x+2y<6
2x+y > or equal too 9 so yea hoped this helped
