I know this is late and you probably got the answer but just in case its C. 5. :P
1. x = 2
2. x = 9
3. a = 3
4. x = 13
5. c = 3
6. s = 3
7. x = 7
8. c = 0
9. b = 1
10. c = 4
11. x = 4
12. x = 8
13. x = 12
14. y = 10
15. x = 11
16. x = 10
17. x = 6
18. x = 11
Answer:
i can only explain it. sorry. if u need help ask
Step-by-step explanation:
so u gotta find a, b, and c.
the first part of a is going to equal x, the other is y(u know what i mean?)
so it says that a= -2, -1. So -2 is the x and -1 is the y.
y= rise/run.
thex=run, and the rise =y.
This will be a little complex number...
assume 35 years ago, it cost x dollars
for now: x×

=25.25
solve it! :) maybe too difficult without a calculator
