Answer:
x = 3 units 
SV = 2 units
Step-by-step explanation:
In QR and ST are chords such that:
 QR and ST are chords such that:
QR = ST = 4 
That is both the chords are equal in measure. 
Equal chords are at equal distance from the center of the circle. Therefore, 
VZ = UZ 
4x - 6 = 6
4x = 6 + 6
4x = 12
x = 12/4
x = 3 units 
Since, perpendicular dropped from the center of the circle bisects the chord.
 
 
 
 

 
        
             
        
        
        
5/12(poetry) + 2/5(biographies) = 25/60 + 24/60 = 49/60
60/60 - 49/60= 11/60
11/60 are the remainder of the books in the shipment.
        
             
        
        
        
7 and 14 can be divided in to two
        
             
        
        
        
Answer:
Option D is correct that is The Slopes of two lines are negative reciprocals.
Step-by-step explanation:
Perpendicular lines are the lines which intersect each other at right angle or make 90° angle with each other.
we that the Slope of perpendicular lines are equal to -1
Therefore, Option D is correct that is The Slopes of two lines are negative reciprocals.
 
        
             
        
        
        
The point-slope form:

m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).
