Mischa wrote the quadratic equation 0 = –x2 + 4x – 7 in standard form
The standard form of quadratic equation is 

When y=0 then the standard equation becomes

Now we compare the given equation  with
  with  and find the value of a, b,c
 and find the value of a, b,c
-x^2 can be written as -1x^2
 
 
 
 
 a= -1 , b=4  and c=-7
The value of c is -7
 
        
                    
             
        
        
        
Answer:
the number (x) is 120.
Explanation:
<em>100% + 60% = 160% = 1.6 </em>
<em />
<em>(just multiply it by 1.6 because it is equal to 60%)</em>
 
        
             
        
        
        
Answer:
y = - 2x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (5, 2) into the partial equation
2 = - 10 + c ⇒ c = 2 + 10 = 12
y = - 2x + 12 ← equation of line
 
        
             
        
        
        
Volume=lengthXwidthXheight 
 far left— 8x8x20= 1280ft^3
middle— 60-8=52-20=32 so you find out the length of just that piece of solid 
20-12=8 to find out width 
8x8x32=2048ft^3
far right— 20x15x8=2400ft^3 
volume of whole shape- add each value together 1280+2048+2400=5728ft^3
volume= measurement^3
