Answer:
x = 9
Step-by-step explanation:
Since both points share the same x-coordinate, look no further.
It has to be a vertical line with x-coordinate 9.
 
        
             
        
        
        
Answer:
6 Chickens
Step-by-step explanation:
Let  H represent the number of horses and  C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C  +  4 H  =  32     (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C  +  H  =  11    (Eq. 2)
From Eq. 2, solve for the number of chickens:
C  +  H  =  11
C   =  11  - H    (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C  +  4 H  =  32
2 ( 11  −  H )  +  4 H  =  32
22   −  2 H  +  4 H  =  32
2H  =  32  − 22
2 H  = 10
H = 5               Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 =  32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
 
        
             
        
        
        
 Answer: 450 cm³ is the volume
Step-by-step explanation:
Volume of pyramid = L x W x H divide by 3
 
        
             
        
        
        
Because x is negative the domain of the function is all negative real numbers.
Set the radical greater than or equal to 0:
-x >= 0
Turn x positive by multiplying both sides by -1. When you multiply an inequality by -1 you need to reverse the inequality sign:
X <= 0
Domain is all real numbers below 0 so all negative real numbers.
 
        
                    
             
        
        
        
So the trapezoid has 2 parallel sides making segments AD and BC  transversals
Therefore making angle c and angle b add up to 180
(180-3x) + 3x + 180-9x +9x
180 +12x = 360
180= 12x
x= 15
