It has two different pairs
Firstly, we will let this mystery number we are finding be labelled as x. Double this number can be written as 2x. 5 less than double this number is written as 2x - 5. And because this number is between -7 and 13, we have the full inequality, -7 < 2x - 5 < 13.
To solve this inequality, we want to isolate x, so we add 5 to all 3 parts of the inequality. Doing so cancels out the - 5 in the middle, so our new inequality is -2 < 2x < 18. Now we want to divide all 3 parts of the inequality by 2 to isolate x, so now our final inequality is -1 < x < 9. Thus, we can say that x is between -1 and 9.
First, you have to find the unit rate by dividing
2000/6=333.33 but round it up to 333
So the unit rate is 333 bacteria per hour
Then, you have to multiply
333x16= 5,328 bacteria after 16 hours
The answer is that in 16 hours, there will be 5,328 bacteria
I hope this helps
Part A) It depends on how long the experiment will be the domain must start from zero and should go as long as the experiment will last.
Part B) y intercept would be the height of the plant after n days
Part C) 8(1.05)^2 = 8.82, 8(1.05)^6 = 10.72
10.72 - 8.82 = 1.9
6-2 =4
1.9 /4 = 0.475
this means the plant grows at an average of 0.475 cm per day
