Answer:
x = -7
Step-by-step explanation:
you have to distribute the 2 to what is in the parenthesis, then you get left with 2x+18=4 so subtract the 18 from both sides leaving you with 2x=-14 so you divide both by 2 leaving you with x=-7.
Question:
A population of insects, in thousands, can be modeled using the function
, where t is time in months. Which statement best
describes the population of insects?
A. The population is decaying at a rate of 3% each month.
B. The population is decaying at a rate of 25% each month.
C. The population is growing at a rate of 75% each month.
D. The population is growing at a rate of 97% each month.
Answer:
A. The population is decaying at a rate of 3% each month.
Step-by-step explanation:
Given

Required
True statement about the function
From the options, we can see that we are to answer the question on the basis of decay and growing rates.
An exponential form is:

Compare to 

If
, then
r represents growth rate
else,
r represents decay rate
Since b < 0.97:





for the first one set 3y+y=180 and y+x=180
the second one set w+y=180, 42+x=180, y+20=180, and 87+v
2. Equals 307.629 because if you line up the decimals when you and then you should get your right answer
Answer:
Yes. They are proportional.
Step-by-step explanation:


The left side 0.777 is equal to the right side 0.777, which means that the given statement is always true.
True
