Answer:
m=25/12
Step-by-step explanation:
multiply the reciprocal of 2/5 on both sides
 
        
             
        
        
        
The answer to the question is d
 
        
        
        
7 is the number increased by 5 = 12
        
             
        
        
        
Answer: Vertex = (2, -15)  2nd point = (0, -3)
<u>Step-by-step explanation:</u>
g(x) = 3x² - 12x - 3
       = 3(x² - 4x - 1)
           a=1   b=-4  c=-1
Find the x-value of the vertex by using the formula for the axis of symmetry: 

       
          = 2
Find the y-value of the vertex by plugging the x-value (above) into the given equation: g(x) = 3x² - 12x - 3
g(2) = 3(2)² - 12(2) - 3
        = 12  - 24 - 3
        = -15
So, the vertex is (2, -15)  ←  PLOT THIS COORDINATE
Now, choose a different x-value.  Plug it into the equation and solve for y. <em>I chose x = 0</em>
g(0) = 3(0)² - 12(0) - 3
        = 0  - 0 - 3
        = -3
So, an additional point is (0, -3)  ←  PLOT THIS COORDINATE
