hope this helps
40-31=x is the equation
Step-by-step explanation:
Dogs: 12% of 45= 5.4
Cats: 24% of 45= 10.8
Fish: 36% of 45= 16.2
Other: 28% of 45= 12.6
Answer:
f(x) = 3(0.2)^x
Step-by-step explanation:
The leading coefficient is 3 as x = 0 gives f(x) = 3.
When x = 1, f(x) = 0.6. so try :
0.6 =3(1.2)^1 = 3.6 so it's not the fiirst choice.
0.6 = 3(0.2)^1 = 0.6 so its last choice.
Check when x = -1:
3(0.2)^-1
= 3/ 0.2
= 15
