The value of the differential with respect to x is -xy/x²+ay
<h3>Implicit differentiation</h3>
Given the following function
x²y +ay² = b
We are to differentiate implicitly with respect to x
x²dy/dx + 2xy + 2aydy/dx = 0
(2x²+2ay)dy/dx = -2xy
dy/dx = -xy/x²+ay
Hence the value of the differential with respect to x is -xy/x²+ay

Step-by-step explanation:
Answer:
$6.83
Step-by-step explanation:
A brownie costs $3.45, an ice cream costs $2.43, and a cookie costs $0.95. So $3.45 + $2.43 + $0.95 = $6.83. If you need to know the change if they paid with $10.00 also . . . That would be $10.00 - $6.83 = $3.17 change.
Answer:
$ 154
Step-by-step explanation
Let the value of suitcase=x
x × 4.5% = 6.93 (converted the question into equation)
x × 
= 6.93 (converted the percentage into fraction)
x = 6.93 x 
(took reciprocal of 4.5/100 after moving it to the other side of the equation)
x = 
(multiplied the values)
x = 154 $ (simplified the fraction)
