A population of bacteria doubles every 12 hours. Initially, the population of bacteria is 80.

A number of bacteria after 30 hours is 480 bacteria.
The answer is 480 because originally the amount was 80. After 12 hours it doubled to 160. Then after 24 hours have passed, the amount doubled again. So now the amount is 320 bacteria. Then 6 hours passed (half of 12 hours) so then you add half of that amount (160) to 320. 320 plus 160 is 480. So the answer is 480

Can someone plz help me with this I am in “confusion”.
kvasek [131]

Answers are 1. a = 32, b = 2, 3. c = 4, 4. x = -3, 5. y = -7, 6. z = -2, 7. m = -7, 8. n = -4, 9. s = -3, 10. r = 5, 11. t = 3, 12. p = 2, 13. x = 9, 14. w = 6, 15. g = 1.5, 16. v = -16, 17. b = -6, 18. h = -5, 19. k = -2.5, 20. d = -3.5, 21. r = -8, 22. z = -9, 23. x = -7, 24. y = 3.5, 25. y = 9, 26. w = 8.

Step-by-step explanation:

Step 1; To solve the given equations we keep the unknown variable on one side while the known numbers are taken to the other side. If both sides are negative the answer has a positive value while if one side is positive and one side is negative, the answer is negative.

Step 2; Solve

1. a = 9/3=  3,

2. b = 14/7 = 2,

3. c = 36/9 = 4,

4. x = -15/5 = -3,

5. y = 28/-4 = -7,  

6. z = -16/8 = -2,

7. m = 28/-4 = -7,

8. n = 8/-2 = -4,

9. s = -21/7 = -3,

10. r = -25/-5 = 5,

11. t = -18/-6 = 3,

12. p = -18/-9 = 2,

13. x = 18/2 = 9,

14. w = 24/4 = 6,

15. g = 9/6 = 1.5,

16. v = -32/2 = -16,

17. b = -18/3 = -6,

18. h = -35/7 = -5,

19. k = 20/-8 = -2.5,

20. d = 14/-4 = -3.5,

21. r = -72/9 = -8,

22. z = 27/-3 = -9,

23. x = -35/5 = -7,

24. y = 28/8 = 3.5,

25. y = 81/9 = 9,

26. w = 16/2 = 8.

Determine which relation is a function.
choli [55]
Hello!

In a function, each input must have only one output. Outputs can have multiple inputs, but each input must have one output. For example, {(4,-1), (4,-2)<span>} is not a function, as 4 has two outputs.

In B, -2 has two outputs, 3 and 1, so it is not the answer.

In C, 3 has two outputs, 5 and 2, so it is not a function.

In D,-1 has two outputs, 1 and 5, so it will not work.

In A, each number has one output, so it is a function.

I hope this helps!</span>

The function G(x)=f(x+3)+2 which of the following is true of the graph of g(x)?
zepelin [54]
G(x)=(x+3)+2

G(x) = (x-h) + k
h translates the graph left/right and k translates the graph up/down.
Because the equation is x- the parenthesis is (x - - 3) which makes h a negative 3 and will translate left. The k positive so it will move up.

State which of the following ordered pairs is a function. Set A: (-1, 0), (-2, 1), (4, 3), (3, 4) Set B: (1, 4), (2, 3), (3, 2),
liubo4ka [24]
Sets A and B are both functions because they all have different x values. Set C is not a function because it repeats the x value of 2 and gives it two different y values.
