Considering the slopes of the segments, the correct option is:
D. No, because the triangle ABC doesn't have a pair of perpendicular sides.
<h3>When are lines parallel, perpendicular or neither?</h3>
The slope, given by <u>change in y divided by change in x</u>, determines if the lines are parallel, perpendicular, or neither, as follows:
- If they are equal, the lines are parallel.
 
- If their multiplication is of -1, they are perpendicular.
 
- Otherwise, they are neither.
 
Here, we have to find if there are perpendicular segments, that is, if two slopes multiplied have a value of -1, then:
- mAB = (-7 - 9)/(11 - 1) = -8/5.
 
- mAC = (3 - 9)/(-9 - 1) = 3/5.
 
- mBC = (3 - (-7))/(-9 - 11) = -1/2.
 
No sides are perpendicular, hence option D is correct.

Answer:
see below
Step-by-step explanation:
2/3y + 15 = 9
Subtract 15 from each side
2/3y + 15-15 = 9-15
2/3y = -6
Multiply each side by 3/2 to isolate y
3/2 * 2/3y = -6 *3/2
y = -9
 
        
                    
             
        
        
        
Since CB || ED and CB = ED, 
by the alternate interior angles theorem, 
mE = mC, and mD = mB. 
with CB = ED, we can conclude that CBF = EDF, by SAS congruent theorem.
        
             
        
        
        
Answer: |p-72% |≤ 4%
Step-by-step explanation:
Let p be the population proportion.
The absolute inequality about p using an absolute value inequality.:
 , where E = margin of error, 
 = sample proportion
Given:  A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .
|p-72% |≤ 4%
⇒    72% - 4% ≤ p ≤ 72% +4%
⇒  68%  ≤ p ≤  76%.
i.e. p is most likely to be between 68% and 76% (.
