Answer:
Possible derivation:
d/dx(a x + a y(x) + x a + y(x) a)
Rewrite the expression: a x + a y(x) + x a + y(x) a = 2 a x + 2 a y(x):
= d/dx(2 a x + 2 a y(x))
Differentiate the sum term by term and factor out constants:
= 2 a (d/dx(x)) + 2 a (d/dx(y(x)))
The derivative of x is 1:
= 2 a (d/dx(y(x))) + 1 2 a
Using the chain rule, d/dx(y(x)) = (dy(u))/(du) (du)/(dx), where u = x and d/(du)(y(u)) = y'(u):
= 2 a + d/dx(x) y'(x) 2 a
The derivative of x is 1:
= 2 a + 1 2 a y'(x)
Simplify the expression:
= 2 a + 2 a y'(x)
Simplify the expression:
Answer: = 2 a
Step-by-step explanation:
Answer:
b(-10)= -6
Step-by-step explanation:
b(x)= |x+4|
b(-10)= |-10+4|
b(-10)= -6
Decrease by 6% = 100 - 6 = 94
Increase this by 19%
= 19/100 x 94
= 17.86
94 + 17.86 = 111.86
\ 100 = 1.1186
The answer is 1 1/40 because u have to change the Denominator
