Answer:
<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ ) </em>
Step-by-step explanation:
x³ - 64x = x( x² - 64 ) ≠ 0 ⇒ x ≠ 0 and x ≠ ± 8
<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ )</em>
Answer:
$47.96
Step-by-step explanation:
Step one - Convert 20% to the fraction 1/5
Step two - Multiply 59.95/5 (equivalent to 59.95*1/5 just easier to write down) to get 11.99
Step three - 11.99*4 because we want to find out what 80% of the cost is (which would be 20% or 1/5 in this case *4)
Answer - $47.96
Hoped this helped
A faster way would be multiplying 59.95 by 4/5 instead as it gives the same result with less steps.
