Answer:
The answer is D. Vertex at (-7,-9).
Step-by-step explanation:
The equation is in vertex form, so you take the opposite of x and the constant stays the same. So, the opposite of 7 is -7 and -9 stays the same.
 
        
             
        
        
        
Answer:
no
Step-by-step explanation:
4x -3 = 16 
x=19/4
4(x-3) = 16: Distribute the number in the parenthesis with 4 and you get:
4x-12=16
x=7
4x-12=16 is not the same as 4x-3=16 
Therefore they do not have the same solution.
