Answer:
y = 27.1
Step-by-step explanation:
We have the value of x: 
x = 12 
and we need to find the value of y in the expression: 
y = x + 15.1
as we can see by the equation, the value of y depends on the value of x.
thus, we substitute x = 12 on the previous equation: 
y = 12 + 15.1
y = 27.1
the value of y is 27.1

The initial velocity: v o = 20 m/s.And :  a = 1.5 m / s² , t = 5 s.The final velocity formula:v = v o + a · tv = 20 + 1.5 · 5v = 20 + 7.5v = 27.5 m /sAnswer: The car`s final velocity is 27.5 meters / second.
        
                    
             
        
        
        
Answer:
C.   (x, y) → (x, -y)
Step-by-step explanation:
The algebraic representation that correctly describes a reflection over the x-axis is (x, y) → (x, -y) 
Here's an example to show understanding 
Plot A is (4,6) and the reflection over the x-axis would be (4,-6)
