Answer:
a.y'=-1
b.y'=-1
c.Yes
Step-by-step explanation:
We are given that consider a function
Implicit function: That function is a relation in which dependent variable can not be expressed in terms of independent variable
Explicit function: It is that function in which dependent variable can be expressed in terms of independent variable.
a.
Differentiate w.r.t x then we get
b.
Differentiate w.r.t x then we get
When we substituting the value of y obtained from part b into a solution of part a then we get
Hence, solutions are consistent.
Answer:
Option (A).
Step-by-step explanation:
is a mixed fraction and can be written as,
[Combination of a whole number and a fraction]
When we multiply this mixed fraction by 7,
[Distributive property → a(b + c) = a×b + a×c]
Therefore, 
will be the answer.
Option (A) will be the correct option.
Answer:
2nd possible answer is the correct one; the const. of var. is 1/3.
Step-by-step explanation:
xy = 1/3 can be rewritten in inverse variation format: Divide both sides by x to isolate y. Then y = (1/3)(1/x). The constant of (inverse) variation is 1/3.
