Factor the following:
126 u + 28 v + 126
Factor 14 out of 126 u + 28 v + 126:
Answer: 14 (9 u + 2 v + 9)
You can take the -1 times the final answer and keep the denominator as positive, or keep track of all the negatives.
That would be choice C the limit of f(x) is 2.
I did some research and I think the answer is 255
Part A:
- Each dollar spent DOES appear to always have the same number of points.
This is correct because it has a set rate of 10 points per dollar.
- Predicted number of points spent for $9:
$9 * 10 = $90
Part B:
- It DOES appear to take the same amount of time to serve each customer.
This is correct because it has a set rate of 4 minutes per customer.
- Predicted number of customers served in 36 minutes: 36/4= 9 customers.
Hope this helps!
