Answer:
x = 21
Step-by-step explanation:
(x+6)^1/3 - 5= -2
add 5 to both sides of the equation:
(x+6)^1/3 = 3
cube both sides of the equation:
x + 6 = 27
subtract 6 from each side:
Answer:
(-∞ , -1) ∪ (4 , ∞)
Step-by-step explanation:
-1 > 3x + 2 or 3x + 2 > 14
-1> 3x + 2 or 3x + 2 > 14
-1 - 2 > 3x or 3x > 14 - 2
-3 > 3x or 3x > 12
-1 > x or x > 4
(-∞ , -1) ∪ (4 , ∞)
Hope it helps :)

Answer:

Step-by-step explanation:
By definition, the derivative of
is given by:

Given
,
must also be
. Therefore, we have:

Note that the derivative of a constant is always zero since for
, where
is some constant,
and we obtain
in the numerator, yielding a final answer of zero.
Answer:
x=31
Step-by-step explanation:
you just have to add the two equations to equal 180 because it's they're supplementary angles.
(25+x)+4x=180
25+x+4x=180
25+5x=180
5x=155
x=31
