Ascientist measured the water temperature at different depths. she made a table showing her findings. the x-values represent the depth, in feet. the y-values represent the temperature in degrees celsius.

x y
0 0
15 3
30 6

assuming there is a proportional relationship, which additional set of values could be included in the table?
a (10, 2)
b (40, 9)
c (50, 38)
d (100, 76)

The correct answer is option a.

Step-by-step explanation:

Given that there is a proportional relationship between x and y.

k = proportionality constant

From data take :

x = 15 , y = 3

k = 5

From the given options, set which will give ratio equal to 5 can be included;

a)

k = 5

b) (40, 9)

c) (50, 38)

d) (100, 76)

Additional set of values could be included in the table is (10,2).

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
