Answer: D. an angle is in standard position if the vertex is at the origin of a rectangular coordinate system and the initial side lies along the positive x-axis.
 
        
             
        
        
        
Easy, find the equation of the line,
Using y=mx+b form:
(-1,3) m=2
3= 2(-1)+b
3= -2+b
+2     +2
5=b
y=2x+5. This is your equation.
Now, plug in the coordinates:
(-3,2)
2= 2(-3)+5
2= -6+5
2= -1
NO
(0,5)
5= 2(0)+5
5=5
YES
(1,5)
5= 2(1)+5
5= 2+5
5=7
NO
(1,4)
4= 2(1)+5
4= 2+5
4=7
NO.
Thus, B, is your answer.
        
             
        
        
        
Expanded form is just each place value split into addition.
so 1,852 is
1000 + 800 + 50 + 2
that's all
        
                    
             
        
        
        
Answer:
The number of machines to complete job in 2 hours is 6.
Step-by-step explanation:
Using the relation of the rate of each one machine and knowing that adding up both rates.
 
Rate R =  'x' is the job
  'x' is the job 
Rate S =  'x' is the job
  'x' is the job 
So, using the equation of rates 
         
Rate total is going to be a job in 2 hours so =
