Answer:

  • A) a = 4, b = 3

Step-by-step explanation:

<h3>#6</h3>

<u>Given equation:</u>

  • 4/(x - 3) + 2/(x - 2) = 2

<u>Multiply all terms by (x - 3)(x - 2):</u>

  • 4(x - 2) + 2(x - 3) = 2(x - 3)(x - 2)
  • 2(x - 2) + (x - 3) = (x - 3)(x - 2)
  • 2x - 4 + x - 3 = x² - 5x + 6
  • x² - 5x - 3x + 6 + 7 = 0
  • x² - 8x + 13 = 0
  • x = (8 ± √(8² - 4*13))/2 = (8 ± √12)/2 = (8 ± 2√3)/2 = 4 ± √3

<u>Compare this to the given form to get:</u>

  • a = 4, b = 3

Correct choice is A

Convert the decimal expansion 0.1777 into a rational number
Helen [10]

Answer:

The rational form of the given number 0.1777  = \frac{1777}{10,000}

Step-by-step explanation:

The rational number is expressed as a number on the form of (\frac{p}{q} ) , q \neq 0

Now,here the given number in decimal form = 0.1777

To remove the decimal, firstly count the number of digits AFTER DECIMAL.

Here, number of digits after decimal = 4

SO, the decimal can be removed and replaced by 1 , by dividing with 1,0000.

\implies 0.1777  = \frac{01,777} {10,000}  = \frac{1777}{10,000}

Hence, the rational form of the given number 0.1777  = \frac{1777}{10,000}
