Answer:
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3).
Step-by-step explanation:
xy = (x + y)^4
Using implicit differentiation:
x dy/dx + y*1 = 4 (x + y)^3 * (1 + dy/dx)
x dy/dx + y = 4 (x + y)^3 + 4 dy/dx (x + y)^3
x dy/dx - 4 dy/dx (x + y)^3 = 4 (x + y)^3 - y
dy/dx( x - 4(x + y)^3) = 4 (x + y)^3 - y
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3)
You're question is:
- 0.35 - (-0.25)
Note that two negatives = one positive
-0.35 - (-0.25) = -0.35 + 0.25
Combine. Subtract.
-0.35 + 0.25 = 0.25 - 0.35
0.25 - 0.35 = - 0.1
-0.1 is your answer

Answer:
7/8
Step-by-step explanation:
To find: number which represents the expression
Solution:
Integers refers to natural numbers, 0 together with negative of rational numbers.
A rational number is the number of the form where p and q are integers and .
So, represents
First, make the mixed fraction into improper fraction,
x−12=54
Add 1/2 on both sides
x−12+12=54+12
Find LCM,
LCM is 4
x=54+1⋅22⋅2
x=54+24
Add
x=74
Or,
x=134
Or,
x=1.75
X=1.75 IS YOUR ANSWER!
Hope this helps!
Have a great day: )
