The amount of military spending M (in biliions of dollars) in the U. S. during year t is given approximately by the equation, M=48.81t + 304.30 where t=0 corresponds to the year 2000. During what year did the military spending in the U. S. hit approximately $694.78 billion

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

true !

step-by-step explanation:

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
