Solve: (1/x)+6 = 5/sqrt(x)

Semenov [28]

<em>Solve: </em> $\frac{1}{x} + 6 = \frac{5}{\sqrt{x}}$

Start by squaring both sides to eliminate the square root.
$(\frac{1}{x} + 6)^{2} = \frac{25}{x}$

Expand the left hand side.
$\frac{1}{x^{2}} + \frac{12}{x} + 36 = \frac{25}{x}$

Simplify.
$\frac{1}{x^{2}} - \frac{13}{x} + 36 = 0$
$\frac{1 - 13x + 36x^{2}}{x^{2}} = 0$

Solve for x.
$36x^{2} - 13x + 1 = 0$
$36x^{2} - 9x - 4x + 1 = 0$
$9x(4x - 1) - (4x - 1) = 0$

$(9x - 1)(4x - 1) = 0$
$\therefore x = \frac{1}{9}, \frac{1}{4}$

Which of the following equations have infinitely many solutions?

Bad White [126]

Answer:

Step-by-step explanation:

A. 6x + 35 = - 6x - 35,

12x = - 70

x = - 70/12

B. - 6x + 35 = - 6x + 35

- 6x + 6x = 35 - 35

0 = 0 infinitely many solutions

C. 6x+35= - 6x+35

12x = 0

x = 0

D. -6x+35= - 6x-35

- 6x + 6x = - 35 - 35

0 = - 70 false, no solutions
