It represents a linear function because there is a constant rate of change.
It represents a linear function because there is not a constant rate of change.
It represents a non-linear function because there is a constant rate of change.
It represents a non-linear function because there is not a constant rate of change.​

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

d=22

step-by-step explanation:

6) 10x + 2 = 32

10x = 30

x = 3

7) 19 - 4c = 17

-4c = -2

c = 1/2

8) 1.1x + 1.2x - 5.4 = -10

2.3x - 5.4 = -10

2.3x = -4.6

x = -2

9) 2/3h - 1/3h + 11 = 8

1/3h = -3

h = -9

10) 6 (5 - 8v) + 12 = -54

30 - 48v + 12 = -54

42 - 48v = -54

-48v = -96

v = 2

11) 21 (2 - x) + 12x = 44

42 - 21x + 12x = 44

42 -9x = 44

-9x = 2

x = -2/9

12) -2 (7 - y) +4 = -4

-14 + 2y + 4 = -4

-10 + 2y = -4

2y = 6

y = 3

13) the cost c ( in dollars) of making n watches is represented by c= 15n + 85. how many watches are made when the cost is $385?

c = 15n + 85

385 = 15n + 85

300 = 15n

20 = n

20 watches
