D
Step-by-step explanation:
BECAUSE 19-11 ISNT 10
Hello! Let's look at the two parts of this question.
Complete the table:
In this case, you just substitute the value of "hour" into the equation, for the value of t. For example:
P(0) = 120 
P(0) = 120 (1)
P(0) = 120
Therefore, the number of bacteria for hour 0 is 120.
You can do this for the next ones. Hour 1 = 240, hour 2 = 480, and so on. (In this case, you can keep multiplying by 2)
Estimate when there will be more than 100,000 bacteria:
Set the final value of P(t) = 100,000, then solve.
100,000 = 120 (2
833.33 = (2
t = 
t = 9.702744108
So your answer would be around 9.7 years, or, around 10 years.
Hope this helps!
Answer:
-3x+12-9x+8=-3(4x-7)
-3x+12-9x+8=-12x+21
-12x+21=-12x+21
21=21
infinitely many solutions
hope this helps
have a good day :)

Answer:
D. x = 1.7 or x = 5.7
Step-by-step explanation:
The left side of the equation is graphed in blue. The right side of the equation is graphed in red.
The solution of the equation is the x (and y) that make both equations true.
On the graph these solutions are the points where the two graphs intersect.
Those two points have x values that are positive (and y's that are negative) Only answer D. has x-values that correspond to the x-values of the points of intersection.
