Answer:
68⁰
Step-by-step explanation:
90 + 22 = 112
180 - 112 = 68
2x + 3y = 10 -> y = -2/3x + 10/3 it's a function
4x = 16 -> x =4 it's not a function
2x - 3 = 14 -> x = 8.5 it's not a function
3y = 18 -> y = 6 it's a function
2x = 6 -> x = 3 it's not a function
Answer:
(B) 
Step-by-step explanation:
we can use formula

where
Po is the initial population
r is the growth rate
t is the time in months
We are given
initial population of insects
so, Po=6
The scientists find that the insect population, x, is growing exponentially 20% per month
so, r=0.20
now, we can plug these values

there to be a population of 477 insects
so, P(t)=477
now, we plug it
and we get

Whats the question? I dont understand whats happenign here.
Subtract 3 from y you get 6(-y)
6*y=6y
