Answer:
The top right answer choice is correct.
2.3 x 12 = 27.6
27.6 > 27.1
Step-by-step explanation:
Well first off, we know that:
1 foot = 12 inches
To compare the two, we first want to covert 2.3 feet into inches.
2.3 x 12 = 27.6 inches
Now that we have our two values, we need to decide which is greater than the other.
27.6   or    27.1
Both values have a decimal that shows tenths. In this problem, 6 tenths is larger than 1 tenth. Therefore:
27.6 inches > 27.1 inches
 
        
             
        
        
        
Answer:  Answer  is in the steps..
Step-by-step explanation:
f(x)=  - 3x -5
 - 3x -5        
A) To find the x intercepts of a parabola we have to set the whole equation equal zero because the x intercept is when y equal zero in other words where f(x) equal zero. 
   - 3x - 5 = 0     Now solve using quadratic formula.
  - 3x - 5 = 0     Now solve using quadratic formula. 
   x = -b± 
    
   x = 3 ±  
  
    x = 3 ±  / 2a
  / 2a 
    x= 3 ± 7 /4
    x= -1   or x = 5/2  
The x intercepts are  (5/2,0)  and (-1,0) 
    
B)  The graph vertex of the graph of f(x)  is going to be at a minimum because the leading coefficient of the function has a positive integer which means the parabola will open up and its vertex will be at the minimum point. 
  Using the  x coordinates  we could find their average and find the x coordinate of the   vertex. 
  =
  =   = 3/4
 = 3/4  
The x coordinate of the vertex  is 3/4 so we will input that into the equation and solve for the y coordinate   
 
 = 18/16 - 9/4 -5  =  -49/8
   = 18/16 - 9/4 -5  =  -49/8 
 The y coordinate of the vertex  is  -49/8 
So the vertex is (3/4, -49/8)  
C)   First  I will graph the vertex and then graph he two x intercepts and connect then like a U shape.
