0.1 is 1/10 of 0.9
You can divide 0.9 by 0.1
        
             
        
        
        
Answer:
x = -2
Step-by-step explanation:
subtract the 6 from 22
then divide -8x and 16 by -8
then you get your anser
 
        
             
        
        
        
Answer:
(-2,4)
Step-by-step explanation:
ordered pair = coordinates 
f(-2) = -2+6 = 4
f(x) = y 
 
        
                    
             
        
        
        
Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of  a man = 'x' miles/hour
Time taken =  hour
 hour
So, distance = product of speed and time.
Distance covered in term of 'x' 
Now,
Speed =  miles/hour
 miles/hour
Time taken=  hours
 hours
Distance  =
  = 
                       = 
                       =  miles
 miles
Total distance covered by the man = Summation of   and
 and 
                                                            = 
                                                            =  miles
 miles
 So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.
 
        
             
        
        
        
Answer:
The last choice is correct.
Step-by-step explanation:
The given function is

This is a parabola with a=1>0. 
The graph will therefore open up.
By comparing to

The vertex is at (h,k)= (-3.8,-2.7)
Therefore the graph crosses the x-axis and the y-axis.
Also the vertex is in the 3rd quadrant because both x and y are negative in this quadrant.
Answer:
On a coordinate plane, a parabola opens up. It starts in quadrant 2, crosses the x axis where the vertex is in quadrant 3, and crosses the x-axis back into quadrant 2.
