Answer:
11. x = -16
12. k = 6
13. x = -19
14. x = -6
15. x = -20
16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?
17. x = 19
18. n = -10
19. b = 11
20. n = 4
21. r = -6
22. n = -4
Again super sorry about question 16 :(
Step-by-step explanation:
11) -1= x/16
x= -16(because when dividing a negative and positive number the answer is always a negative.
12) 7=1+k
k=7-1
k=6
13) x-6=-25
x=-25+6
x=-19
14) -8x=48
x=48/-8
x= -8
15) x/10=-2
x=10*-2
x=-20
Option C, F(x) = (x+2)/(x+1)

I believe the correct answer is B.
a
a.b=[-1]
This is a dot product of a and b
a.b =[6,-2,3].[2,5, -1] = [12-10-3] =[-1]
