Answer:
(–∞, 0)
Step-by-step explanation:
The graph of the absolute value parent function f(x) = |x| is shown in the attached diagram.
We can clearly see that from -∞ to 0, the function is decreasing and from 0 to +∞, it is increasing. This is the basic, parent absolute value function.
THe questions asks, when is it decreasing, so clearly, it is from -∞ to 0.
This is the answer.
<span>The reflexive property of equality states that a value is equal to itself. (i.e. for all real numbers, x = x.</span>)
Given that the reason for the missing statement, it means that the similarlity statement is equal to it self.
Having proved in statement 3 that <span>∠AEC ≅ ∠BDC both being right angles, it can be seen that the angle both have in common is angle C.
Thus, to statement 4 shows that angle C is congrent to itself.
Therefore, the missing statement in step 4 is </span><span>∠ACE ≅ ∠ACE</span>
