Answer: 475 adults paid admission
Step-by-step explanation:
1.50c+4a=5050 (1.50 per child and 4 per adult)
1.50(2100)+4c=5050 (2100 children times 1.5 each)
3130+4a=5050
4a=1900
a=475
 
        
             
        
        
        
Answer:   D.  y = -4x + 4 
Step-by-step explanation:
Notice that the y-intercept is when x is zero and the x intercept is when y is 0. 
and to write in the equation in slope intercept form , you will need the slope and the intercept. 
We will use the y and x intercepts to find the slope, by find the difference in their y coordinates and dividing it by the difference in their x coordinates.
y intercept: ( 0,4)  
x intercept: (1,0) 
y coordinates difference:  4 - 0 = 4 
x coordinates difference:  0 - 1 = - 1  
Slope:  4/-1 =  -4  
Since the slope is -4 and the the y intercept is 4 , the equation will be 
  y = -4x + 4
