Answer:
x=9
Reverse. 14-5=9, so x must be 9.
 
        
                    
             
        
        
        
v = w - 20
move -20 to the other side
sign changes from -20 to +20
to get w by itself
v+20= w-20+20
Answer:
w= v+20 or w= 20+v
 
        
                    
             
        
        
        
Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right. 
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right. 
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong. 
The D value (Domain) is actually [2, ∞) 
The R value (Range) is actually "All real numbers" (-∞, ∞)
Let me know if this helps!
 
        
             
        
        
        
I believe the answer is .09625 hours 
Explanation: first you do 2.2 x 105= 231
Then you do 231/40=5.775 to get how many minutes it takes to type 231 words. Then u divide 5.775/60 to get how many hours it would take.
