Answer:
y = -2(x + 1)^2 + 8
Step-by-step explanation:
The equation of a parabola can be written in the form;
y = a(x-h)^2 + k
where a is the multiplier (h,k) is the vertex 
so h = -1 and k = 8
Plug in these values 
y = a(x + 1)^2 + 8
So to get the value of a, we use the point where the parabola passes through which is the point (1,0)
Simply substitute the values of x and y 
0 = a(1 + 1)^2 + 8
0 = a(2)^2 + 8
-8 = 4a
a = -8/4
a = -2
So therefore the equation of the parabola is ;
y = -2(x + 1)^2 + 8
 
        
             
        
        
        
D is the correct answer
x+5=10: subtract 5 from both sides the 5 will cancel out leaving x=5 
x+5=10
 -5 -5
x=5
        
             
        
        
        
1.  Parenthesis: 
(15)8 - 4 + 2 + 1
Multiply: 
120 - 4 + 2 + 1
Subtract: 
116 + 2 + 1 
Add: 
119, the answer is A.
2. 8 x 15 = 120
120 / 2 = 60 
6 x 15 = 90 
90 + 60 = 150
The answer is A. 
Hope this helps!
