Answer:
Just list all the coefficients.
Step-by-step explanation:
one thing to know
If a variable is just there, like x, it's coefficient is always a one
1. (12 and 4)
2. (46 and 10)
3. (12 and 14)
4. (10 and 10)
5. (17 and 32)
6. (5,7 and -12)
7. (36 and 70)
8. (3,19 and 10)
9. (7 and 16)
10. (8 and 5)
11. (9 and 120)
12. (12 and 1)
13. (7,15 and 1)
14. (4,-8 and 12)
15. (6,17, and -35)
Finding the slope using two points:
The formula for slope is
In this case you have the points (-3, 5) and (4, 5):
^^^Plug these numbers into the formula for slope...
0
^^^This is your slope

Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
−
2
to the previous term in the sequence gives the next term. In other words,
a
n
=
a

+
d
(

)
.
Arithmetic Sequence:

Answer:
9 weeks
Step-by-step explanation:
Knowing that the "q" is the total number of quizzes, you can set the equation equal to 12, and solve for w.
12 = w + 3 Subtract 3 both sides
9 = w
