Answer:
(a) M = 0.25n +100
Step-by-step explanation:
The distance between the dots on the graph is a rise of 1 grid square and a run of 2 grid squares. If we extend the sequence of dots to the left, we expect to place one at (0, 100). That is, the y-intercept of this function is 100 (eliminates choices C and D).
The rise of 1 grid square represents 25 kg, and the run of 2 grid squares represents 100 CDs. Then the slope of the function (rate of change) is ...
slope = rise/run = 25/100 kg/CD = 0.25
Then the equation describing the points on the graph will be ...
M = 0.25n +100
The domain is (-infinity, +infinity)
The range is (5, +infinity)
1)Calculate the product:
21a + 10a - 3a
2)Collect like terms:
28a
Answer:
28a
Here is your answer:
Your answers Graph A.
Reason: That's because the given line starts on the quarter by 1 which equals .25 and goes up to 6.
You're answer is A.
