Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous

Dmitriy789 [7]

Answer:

Solution: $x=-\frac{1}{5}$ , $x=0$

Step-by-step explanation:

Given:

The rational equation to solve is given as:

$\frac{x}{6}=\frac{x^2}{x-1}$

Doing cross product, we get:

$x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}$

Now, for $x=0$ , the rational equation is equal to 0. So, $x=0$ is a solution.

Also, $x=-\frac{1}{5}$ is also a solution.

So, no extraneous solution.

The equation for the area of a circle is A = πr².

If you double the radius, the area increases exponentially by a factor of two. The area will be squared.

Please I need Help Im confused

vitfil [10]

Answer:

x=3.5 y=8

Step-by-step explanation:

Remeber, in a rectangle, opposite sides are equal so

$2x + 3y = 31$

and

$2x + 1 = y$

Subsitue 2x+1 for y.

$2x + 3(2x + 1) = 31$

$2x + 6x + 3 = 31$

$8x + 3 = 31$

$8x = 28$

$x = 3.5$

Plug this back in to one of the equations to find y.

$2x + 1 = y$

$2(3.5) + 1 = y$

$7 + 1 = y$

$8 = y$

So x=3.5

y=8
