Answer:
Study 1 Answers: 
1) 0.76 represents the multiplier of the bacteria, in this case it is decreasing by 24% because the formula for exponential decay is 1 - r.
2) 1290 represents the initial value, or before the study began. 
Study 2 Answers: 
1) 1180 is the initial value, or before the study began.
2) Study 1 started with more bacteria 
3) Study 1 is experiencing exponential decay, while study 2 is experiencing exponential growth
Step-by-step explanation:
Exponential functions are in the form  , where a is the initial value, b is the multiplier, and x represents inputs, such as hours after a bacteria study.
, where a is the initial value, b is the multiplier, and x represents inputs, such as hours after a bacteria study.
Any multiplier above 1.00 is experiencing exponential growth, meaning it grows gradually over time, and any multiplier below 1.00 is experiencing exponential decay, meaning it decreases in population over time.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
1. 6x + 10 = 6x - 8
    10≠-8
no solution
2. 6x + 8 = 2x - 6
     4x + 8 = -6
      4x = -14
      x = -14/4= -7/2 one solution
3. 9x - 27 = 9x - 27
     0 = 0 All real no. infinitely many solution
 
        
             
        
        
        
Answer:
Step-by-step explanation:
First, the y-intercept is -3 so from -3 the slop to the next point is 4/1.
 
        
             
        
        
        
Answer:
y + 1 = -1/2(x - 8)

<u>Pre-Algebra</u>
Order of Operations: BPEMDAS
- Brackets
- Parenthesis
- Exponents
- Multiplication
- Division

<u>Algebra I</u>
Slope Formula: 
Point-Slope Form: y - y₁ = m(x - x₁)  
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
f(8) = -1 → Coordinate (8, -1)
f(6) = 0 → Coordinate (6, 0)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute [SF]:                     
- Add/Subtract:                       
- Simplify:                                
<u>Step 3: Write Function</u>
<em>Substitute into general form.</em>
- Point 1: y + 1 = -1/2(x - 8)
- Point 2: y = -1/2(x - 6)
