Eight less a number is less than or equal to seventeen
allsm [11]

Answer:

n ≥ -9  

Step-by-step explanation:

Let n = the number

8 <em>less than</em> a number means "n – 8", but

8 <em>less</em> a number means "8 – n," so

8 – n ≤ 17     Subtract 8 from each side

    -n ≤ 9      Multiply each side by -1

    n ≥ -9

<em>Note</em>: When we multiply by a negative number, we must reverse the inequality.

<em>Check:</em>

Try n = -8.

8 – (-8) ≤ 17

  8 + 8 ≤ 17

       16 ≤ 17

<em>True</em>.

Find the LCD of the given rational equation: -3/x+2 + 5x/x-1 = x+2/x^2-3x+2
Natali [406]
Answer:

(x - 1)( x - 2) (x + 2) = x³ -x² -4x + 4.

Explanation:

1) Given equation:

    3             5x            x + 2
- ------- +  -------- =  ---------------
 x + 2        x - 1       x² - 3x + 2

2) So, the denominators are x + 2, x - 1, and x² - 3x + 2

3) The LCD is the product of the common and non common factors raised to the greatest power.

4) x + 2, and x - 1 are already prime factors

5) Factor x² - 3x + 2

x² - 3x + 2 = (x - 2)(x - 1)

6) Then, the factors are x + 2, x - 1, and x - 2, and the LCD is the product of them:
(x - 1)( x - 2) (x + 2)

7) If you expand the products (distributive property) you get:
x³ -x² -4x + 4.
