ZanzabumX [31]

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)

You are choosing between two health clubs. Club A offers membership for a fee of plus $18 a monthly fee of $20 Club B offers mem
AlexFokin [52]

Answer:

x=5

Step-by-step explanation:

so after five months, the costs would equal each other.

Explanation:

You'd have to write equations for the price per month for each club.

Let x equal the number of months of membership, and y equal the total cost. Club A's is y=25x+40 and Club B's is y=30x+15.

Because we know that the prices, y, would be equal, we can set the two equations equal to each other.

25x+40=30x+15.

We can now solve for x by isolating the variable.

25x+25=30x.

25=5x.

5=x

After five months, the total cost would be the same.
