In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .
Answer:
402.12
Step-by-step explanation:
There are many ways you can write a ratio. They're all basically the same thing, though. 5:9, 5 to 9, and 5/9 (which is a fraction) are all just different ways to write ratios.
Answer:
6/30
Step-by-step explanation:
20 percent of 30 is 6 ^_^
Solution:
Numerator - 4x + y = 8 + 4 = 12
Denominator - 2y - x = 8 - 2 = 6
Final Answer:
