Answer:
Step-by-step explanation:
dy/dx= -(2x+3y+1)/(3x-2y+1)
Let x= X+p. and y = Y+q. then dy/dx = dy/dX.
dy/dX= -(2X+2p+3Y+3q+1)/(3X+3p-2Y-2q+1) =
dy/dX = -{2X+3Y+(2p+3q+1)}/{3X-2Y+(3p-2q+1)}
Now 2p+3q+1=0……………..(1)
3p-2q +1=0…………………………(2)
p/(3+2)=q/(3–2)=1/(-4–9)
I have a feeling, these were the answer choices you were trying to make: <span>A ∪ B = {7}
B ⊆ B
B ⊂ A Also, the second answer is the only one that's true

To make the subtraction easier, we can rewrite 11 pounds 5 ounces as
10 pounds 21 ounces then we subtract
1 pound 15 ounces giving us the net weight of
9 pounds 6 ounces.
