Solve. open parentheses square root of 7 close parentheses to the 6 x power = 49x-6
Sveta_85 [38]
The equation is(√7)^6x = 49x - 6
This equation can be solved by iteration.

Rearranging:
x = ( (√7)^6x + 6 )/49

We start with a value of x = 3.
This value can be substituted to the right side and new value of x can be obtained. This new value can be substituted again to the right side of the equation and another new value for x is obtained. This process is repeated until the old and new values of x are the same.

The result is,x = 0.5

Solve y = f(x) = (2x+1)^1/2<br><br> &amp; g(x) = x-1
snow_lady [41]

Answer:

f(x) = x = \frac{y^{2} - 1}{2}

g(x) = 1

Step-by-step explanation:

y = (2x + 1)^1/2

y^{2} = 2x + 1

y^{2} - 1 = 2x

\frac{y^{2} - 1}{2} = x

y = x - 1

y + 1 = x
