Domain: x is greater than or equal to 7
Range: y is greater than or equal to 9
 
        
                    
             
        
        
        
1 year=52 weeks
So just multiply it by 56
52*56= 2912 glasses per year
        
             
        
        
        
Answer:
i can't answer this but i can tell you this
The general form of an absolute value function is f(x)=a|x-h|+k. From this form, we can draw graphs.
y = a(x – h)2 + k, where (h, k) is the vertex. ... In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.
Step-by-step explanation:
it is not the answer but i hope it helps:)
 
        
             
        
        
        
Answer:
20 students
Step-by-step explanation:
If the class decreased by 15%, the students that she has now (17) represents a percentaje of: 
100% - 15% = 85% 
so<u> the 17 students are 85% of what she had</u>:
Students         Percentage
       17          ⇒        85%
and we are looking for how many students she had 2 years ago, thus we are looking for the <u>100%</u> of students (the original number of studens). If we represent this number by x: 
Students         Percentage
       17          ⇒        85%
       x          ⇒        100%
and we solve this problem using the <u>rule of three</u>: multiply the cross quantities on the table( 17 and 100) and then divide by the remaining amount (85): 
x = 17*100/85
x = 1700/85
x=20
2 years ago she had 20 students
 
        
             
        
        
        
The answer is 0.0017. Do you not have a calculator?
