Answer:
A dependent variable is a variable (often denoted by y ) whose value depends on that of another. so it is the variable that changes depending on the numbers beside it.

Recall the definition of absolute value.
When 
,
When ,
The derivative does not exist at 
, since the one-sided limits
and
do not match.
So the derivative of 
is
Now we can write this as
since
and
Log shows exponent in wich you need to put base to get x,
so you have the only choice here it is A,
<span> 3^2 = x , here is the base 3, exponent 2,
</span>A. Log base of (3) x = 2
Answer:
114
Step-by-step explanation:
Supplementary means that all the angles in your givens add up to 180 degrees.
Givens
<A + <B = 180
<A = 2x + 6
<B = x + 3
Solution
<A + <B = 180 Substitute for <A and <B
2x + 6 + x + 3 = 180 Combine like terms on the left.
3x + 9 = 180 Subtract 9 from both sides
3x = 180 - 9
3x = 171 Divide by 3
x = 171/3
x = 57
That's not your answer.
<A = 2x + 6
<A = 2*57
<A = 114
