It would be C because |-6| + |4| is basically 6+4 because the lines make the number positive. 6+4 is 10, which is the x value for the point. That 4 unites us the distance between the points.
        
             
        
        
        
Answer:
Option B. 
Step-by-step explanation:
we know that
The area of a circle is equal to

we have

substitute

Remember that
 radians subtends the complete circle of area
 radians subtends the complete circle of area 
so
by proportion 
Find the area of the related sector for a central angle of  radians
 radians
Let
x------> the area of the related sector

 
        
             
        
        
        
Answer:
1. b+15=27
2. 4*X=36
3. y-9=12
4. k/7=21
Step-by-step explanation:
sum means addition and product means to multiply and difference means subtraction and divided means to divide :)

hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -7  and b = -1 (Center at: A(-7,-1) )
r = AP.... P(8,7)
r² = (AP)²
r² = (8+7)² +(7+1)² =225+64=289 ...... so : r = 17
an equation of the circle that satisfies the stated conditions.
Center at  </span></span>A(-7,-1), passing through P(8, 7) is :  
(x+7)² +(y+1)² = 289
The point (-15,y ) <span>lies on this circle : (-15+7)² +(y+1)² = 289....(subsct : x= -15)
(y+1)² = 225
(y+1)² = 15²
y+1 = 15   or y+1 = -15
y = 14  or y = -16
you have two  points : (-15,14)  , (-15, -16)</span>
