The class is weighted as follows:
60% Regular Tests
10% Final Exam
15% Project
15% Homework
The total weighted points possible for the class are as follows:
(100+100+100+100+100)*.6 + 100*.1 + 100*.15 + 100*.15 = 340
To calculate her individual final weighted grade we plug in her scores for each category and complete the following computation:
(92+83+77+84+82)*.6 + 88*.1 + 95*.15 + 77*.15 = 285.4
So her weighted grade percent would be 285.4/340 = 83.9% which is a B.
 
        
             
        
        
        
This is solved for all values of 
y = -x-3. (Assuming you meant that 2x+2y=-6).
        
             
        
        
        
Answer:
The smallest number n could be is 64.
Step-by-step explanation:
35 + 64 = 99
64/8 = 8
 = √289 = 17
 
        
             
        
        
        
y² - 4y - 2x - 4 = 0
<u>            +2x +4 </u>   <u>+2x + 4 </u>
y² - 4y              = 2x + 4
<u>             +4    </u>      <u>       +4 </u>      
  (y - 2)²          = 2x + 8
<u>              -8   </u>      <u>      -8 </u>
  (y - 2)²  - 8   = 2x

(y - 2)² - 4 = x
x = 
(y - 2)² - 4
<em>Note: this is a parabola whose axis of symmetry is y = 2 and vertex is (-4, 2)</em>
 
        
             
        
        
        
My answer may not be correct but I feel pretty confident. The answer is $549.08
