I = Prnwhere I is the interest, P is the principal, r is the decimal equivalent of the given rate, and n  is the number of years. In this item, we assume that n is equal to 1. Solving for the interests,                $200:     I = ($200)(0.03)(1) = $6                $150:     I = ($150)(0.03)(1) = $4.5The difference between the two calculated interests is $1.5. 
Therefore, you could have earned $1.5 more if you invested $200 rather than $150. 
hope this helps (^>^)
        
             
        
        
        
The general equation for slope-intercept form is y = mx + b, where m = the slope of the equation, b = the y intercept, and x and y are your variables (and the coordinate points on the graph). 
Remember that for parallel lines, the slope, m, is the same for both equations. The equation you're given, y = 2x - 2, is already in slope-intercept form and the 2 in front of x is m, your slope. That means for whatever equation we come up with, m has to be 2. 
So far we know the equation for our parallel line is y = 2x + b. How do we figure out b? Plug in the (x, y) coordinate you're given, (1, 1) and solve for b:

Now we know b = -1. Put that into our y = 2x + b equation to get the final equation of your parallel line: 
Your final answer is y = 2x - 1.

Answer:
<h2>248 Songs</h2>
Step-by-step explanation:
<h3>
Step 1; Set up an equation</h3>
4l + 6l + l = 682
<h3>Step 2: Add like terms</h3>
11l = 682 
<h3>Step 3: Divide by 11</h3>
l = 62
Lou has 62 songs
<h3>Step 4: Multiply by 4</h3>
Kelly has 248 songs
<h3>Step 5: Check</h3>
Kelly has 248 songs
Lou has 62 songs
Tiffany has 372 songs
Is 248 4 times 62? ✔
Is 372 6 times 62? ✔
Is 248 + 372 + 62 = 682? ✔
<h3>Step 6: Answers</h3>

ANSWER

EXPLANATION
The vertex of the graph is at 

The equation of the graph in vertex form is given by the formula,

The above graph has a minimum point, hence 

When we put these values into the equation we obtain,

This implies that,

The point (-2,0) lies on the line.



The correct answer is D.
