Answer:
And the results would apply to every fonction.
 
        
                    
             
        
        
        
Y= mx+c 
So m= the gradient (slope)
And c=the y intercept (x,y= -3,4)
So it should be 
Y=1/3x+4
        
             
        
        
        
Answer:
0.330
Step-by-step explanation:
Divide the number of hits (189) by the number of bats (572)
189/572=0.330
 
        
             
        
        
        
Answer:
81
Step-by-step explanation:
Given the expression: 
To make it a perfect square, we follow the following steps.
Divide the coefficient of x by 2
- Coefficient of x=18, 18/2=9
Square It
Add it to the expression
This is written as a perfect square as: 
The constant term required therefore is 81.
 
        
                    
             
        
        
        
Let
x-------> the amount of  solution
 solution
y--------> the amount of  solution
 solution
we know that
 
 
so

 -------> equation A
 -------> equation A
 -------> equation B
 -------> equation B
substitute equation A in equation B




find the value of y


therefore
The student need  of
 of  solution and
 solution and  of
 of  solution
 solution 
<u>the answer is</u>
A) The percent values were written incorrectly in the equation
B) The amount of 7% solution should be written as 1 – x, not x – 1.
