Find the derivative of the curve to find the line slope at the given point
sqrt(xy) + 4 dy/dx = 39
0.5(xy)^(-0.5) * (y + x dy/dx) + 4dy/dx= 0
No need to amplify simply plug in the given point ( 1,9)
0.5 ( 1 * 9)^(-0.5)* ( 9 + dy/dx) + 4dy/dx = 0
Solve for dy/dx
1/6( 9 + dy/dx) = -4dy/dx
9 + dy/dx = -24 dy/dx
-25dy/dx = 9
dy/dx = -9/25
as your question implies , you know the rest of the steps.

No, they are equal, you can reduce 2/6 to 1/3 divide 2 by 2 and 6 by 2 :)

Let's solve it step-by-step.
5+ 2a/-3= 5/11
Step 1: Simplify both sides of the equation.
5+ 2a/-3= 5/11
-2/3a+5=5/11
Step 2: Subtract 5 from both sides.
-2/3a+5-5=5/11-5
-2/3a=-50/11
Step 3: Multiply both sides by 3/(-2).
a=75/11
So, the answer is a=75/11.
