Answer: I think the answer is B
Step-by-step explanation:
8(x-4) = 8(1-4) = 8-32
2(4x-16) =2(4*1-16) = 8-32
8(x-4) = 8(2-4) = 16-32
2(4x-16) = 2(4*2-16) = 16-32 
 
        
                    
             
        
        
        
Answer:
x=1 and x= -2.5
Step-by-step explanation:
✯Hello✯
The quadratic formula is x=-b+-(sqrt)b^2-4ac/2a
A = 2
B= 3
C = -5
PLUG THESE VALUES INTO THE QUADRATIC FORMULA 
we can see that x=1 and x= -2.5

Answer:
y = -cos(2x)
Step-by-step explanation:
Mean/mid line: y = 0
It's a negative cos, with period pi.
So, y = -cos(2x)
 
        
             
        
        
        
Answer:
Rita = 300
John = 900
Rodell = 925
Step-by-step explanation:
rita = x (let
john = 3x ( john swims three times more than rita
rodell = 25 + 3x ( rodell swims 25 more than john 
x + 3x + 25 + 3x = 2125 
or, 7x + 25 = 2125
or, 7x = 2125 - 25
or, x = 2100/7
 x = 300
hence, 
 x = 300
 3x = 3 × 300
 = 900
 25 + 3x = 25 + 900
 = 925
