Y= -1/2x - 4
hope this helps! :)
hii! i just wanted to say hope you're having a fantastic day and hope that things are going well (: stay strong and stay safe!
Answer:
You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.
Next hour, it triples again so you now have 1 x 3 x 3=9
You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).
Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:
n x 324 where n is the number of bacteria you begin with.
Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer
3^2 + 16
= (3 • 3) + 16
= 9 + 16
= 25

Answer:
x = ± 
Step-by-step explanation:
9x² - 4 = 0 ( add 4 to both sides )
9x² = 4 ( divide both sides by 9 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
= ±
