Answer:
B. Zero
Step-by-step explanation:
The slope of the line is in the the first two quadrants and is horizontal, meaning it has zero slope.
<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>
Answer:
do u have a ss or is this all
Step-by-step explanation:
So, x^2 + 14 x + 49 - 4 = 0;
Then, we use the formula ( a + b )^2 = a^2 + 2ab + b^2;
We have ( x + 7 )^2 - 2^2 = 0;
Then, ( x + 7 )^2 - 2^2 = 0;
We use the formula a^2 - b^2 = ( a - b)( a + b );
We obtain ( x + 5 )( x + 9) = 0;
Then, x + 5 = 0;
x = -5;
x + 9 = 0;
x = - 9;
-5 and - 9 are the zeros of the quadratic function.
