If x+1/x=7,find x^2+1/x^2​
trapecia [35]

Answer:

x²+1/x² = 51

Explanation:

Given x - 1/x = 7 ---(1)

We know the algebraic identity:

a²+b²-2ab = (a-b)²

Or

a²+b² = (a-b)²+2ab

Now,

x²+1/x²

= (x-1/x)²+2*x*(1/x)

= (x-1/x)²+2

:7²+2 [ from (1)] =

= 49+2

= 51

Therefore,

x²+1/x² = 51

The constant of proportionality is always the point___________, where k is the constant of proportionality
TiliK225 [7]
Let's take as example a linear function of the form:
 y = kx.
 Where,
 k is the constant of proportionality.
 Therefore, the proportionality constant is the point:
 (x, kx)
 Generically it is always the point:
 (x, k * f (x))
 Where, f (x) is a function proportional to x.
 answer:
 The constant of proportionality is always the point (x, k * f (x)), where k is the constant of proportionality.
