Answer:

1 solution

Step-by-step explanation:

$y = - 3 \\ y = - x - 4 \\ = > - 3 = - x - 4 \\ = > - x - 4 + 3 = 0 \\ = > - x - 1 = 0 \\ = > - x = 1 \\ = > x = - 1$

X=2 because first you have to combine like terms. Than you have to bring the Varible on one side. Finally you solve for the Varible and you get the answer2.

Answer:

(B) $477=6(1+0.20)^t$

Step-by-step explanation:

we can use formula

$P(t)=P_0(1+r)^t$

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

$P(t)=6(1+0.20)^t$

there to be a population of 477 insects

so, P(t)=477

now, we plug it

and we get

$477=6(1+0.20)^t$
