Answer:

Option A) There is only one solution: x = 1. The solution x = 3 is an extraneous solution.                

Step-by-step explanation:

We are given the following equation:

\displaystyle\frac{1}{x} + \frac{1}{x-3} = \frac{x-2}{x-3}

Solving the given equation, we have:

\displaystyle\frac{1}{x} + \frac{1}{x-3} = \frac{x-2}{x-3}\\\\\frac{2x-3}{x(x-3)}=\frac{x-2}{x-2}\\\\2x-3 = x^2 - 2x\\x^2 - 4x + 3 = 0\\x^2 - x-3x + 3 = 0\\x(x-1)-3(x-3) = 0\\(x-3)(x-1) = 0\\x =1, x=3

Extraneous solutions:

  • An extraneous solution is not a root of the original equation because it was excluded from the domain of the original equation.
  • We may arrive to this solution but cannot consider it as a solution because it is not valid.

But x = 3 cannot be a solution to the given equation as when put in the given equation it gives denominator zero.

Thus, x = 1 is the solution of the given equation and x = 3 is an extraneous solution.

Answer:

The width is 88

Step-by-step explanation:

<u>Perimeter of a rectangle:  2L + 2W</u>

<u />

<u>Step 1:  Solve for W</u>

374 = 2(99) + 2W

374 - 198 = 198 + 2W - 198

176 / 2 = 2W / 2

88 = W

Answer:  The width is 88

Alexander says that 3x + 4y is equivalent to (3)(4) + xy because of any order, any grouping. Is he correct why or why not
snow_lady [41]

Answer:

Alexander is incorrect because the expressions are not equivalent.

Step-by-step explanation:

If the expression is evaluated for any value of x, y; the result will not be same.

For instance, let assume x = 1 and y = 2

3x + 4y = 3 + 4 = 7

(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14

So, the expressions are not the same and Alexander is incorrect.

20 points pls help no links
aniked [119]

Answer:

(-15, 13)

Step-by-step explanation:

-3(8x + 9y = -3)

4( 6x + 7y = 1)

-24x - 27y = 9

24x + 28y = 4 (add both equations)

y = 13

6x + 7*13= 1

6x + 91= 1

6x = 1 -91

x = -91/6

x = -15
