Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms on the right side.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b
Comparing like terms with - 6x² + 12x - 15
x - term → - 3a = 12 ( divide both sides by - 3 )
a = - 4
constant term → - 3b = - 15 ( divide both sides by - 3 )
b = 5
Answer:
4
Step-by-step explanation:
4 x 4 is 16 * dabs*
Answer:
See explanation below.
Step-by-step explanation:
a) c(0) = 10
Here, t = 0 and c(0) = 10
At 8 A.M., there are 10 customers.
b) c(6) = c(7)
6 hours after 8 am is 2pm
7 hours after 8 am is 3pm
They are equal. So it means
There are the same number of customers at 2pm and at 3pm
c)
c(k) = 0
There are no customers, k hours after 8 am
d)
c(4) > c(3)
4 hours after 8 am is 12pm
3 hours after 8 am is 11am
This means:
The number of customers at 12pm is greater than the number of customers at 11am
The < and > signs mean the open part of < or > is bigger part
