<span>The vertex form of a quadratic is given by. y = a(x – h)2 + k, where (h, k) is the vertex. The "a" in the vertex form is the same "a" as. in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.</span><span>

Answer:
The graph below shows the answer to
2x - 3y < 12
Also shown as 
-3y < -2x + 12
Step-by-step explanation:
You can rearrange the inequality by subtracting 2x from both sides to isolate the y.
You now have -3y < 12 -2x
which can be put into the standard linear equation form of 
-3y < -2x + 12
Then you divide both sides by -3 to get singular value of y, which is something like
-3/-3y < -2/-3x + 12/-3 
which is 
y > 2/3x -4
Note: I switched direction of the inequality because you are dividing both sides by a negative value.
 
        
             
        
        
        
97/2 = 48.5
take the whole number below and above that
48 + 49 = 97
