Answer:
The rate of change is <em>17.9 dollars per year</em>.
Step-by-step explanation:
We use the rate of change formula: 
where y2 and x2 and the y and x points respectively of the second point, and y1 and x1 are the y and x points respectively for the frist point.
In our case, the first point's x is 2003 (earlier date) and y is 551 (price).
The second point's x is 2013 (date) and y is 730 (price).
Plugging in the numbers, we get 
This means the rate of change is 17.9 dollars per year.
Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d - 2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.
Answer:
y = 0
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel. Then segment CD must be parallel to AB, and CB must be parallel to DA. Two different segments are parallel if they have the same slope.
slope of DA = (yA - yD)/(xA - xD) = (4 - 2)/(1 - (-1)) = 1
slope of CB = (yB - yC)/(xB - xC) = (2 - yC)/(1 - (-1)) = 1
(2 - yC) = 2 * 1
2 - 2 = yC
0 = yC
Note: coordinates of A are (xA, yA), of B are (xB, yB), of C are (xC, yC) and of D are (xD, yD)
