Answer:

Step-by-step explanation:

Definition of an absolute value is:

|a|=\left \{ {{a, if a\geq 0} \atop {-a, if a

<em>1).</em> Assume that (y + 2) ≥ 0, then

y + 2 > 6 ⇒ <em>y > 4</em>

<em>2).</em> Now, if (y + 2) < 0, then

- (y + 2) > 6 ⇔ - y - 2 > 6 ⇒ <em>y < - 8</em>

<em>y ∈ ( - ∞ , - 8) ∪ (4 , ∞ )</em>

[(4x + 15) / 5x)] = 1/2
Arada [10]
One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:

<span>[(4x + 15) / 5x)] = 1/2  could be written as:

4x + 15        1
----------- =  ---
     5x           2

Then 8x + 30 = 5x

3x = -30,  and so     x = -10 (answer).  Be certain to check this answer through substitution!
