Sep 11, 6:11:06 PM During a snowstorm, Vani tracked the amount of snow on the ground. When the
storm began, there were 2 inches of snow on the ground. Snow fell at a constant rate
of 2 inches per hour until another 10 inches had fallen. The storm then stopped for 2
hours and then started again at a constant rate of 1 inch per hour for the next 7 hours.
As soon as the storm stopped again, the sun came out and melted the snow for the
next 3 hours at a constant rate of 4 inches per hour. Make a graph showing the inches
of snow on the ground over time using the data that Vani collected.

do practice tests.

note: the best i know.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
