Answer:
No, 4+5(6t+1) EQUALS 9+30t
And 9+30t Equals 3(3+10t)
Step-by-step explanation:
GCF=3
3(9/3 + 30t/ 3) =
3(3+10t)
And
4+5(6t+1)
4+30t+5
30t+ (4+5)
Simplifying =
30t+9
Answer:
<h2>
After 5 hours</h2>
Step-by-step explanation:
If a scientist counts 35 bacteria present in a culture and finds that the number of bacteria triples each hour and the function y = 35 ∙ 3x models the number of bacteria after x hours, in order to estimate when there will be about 550 bacteria in the culture we will substitute y = 550 into the modeled equation and calculate the value of x as shown;
If y = 35*3x
when y = 550
550 = 35*3x
Dividing both sides by 35;
550/35 = 35*3x/35
3x = 550/35
x = 550/3*35
x = 550/105
x = 5.24
This means that there will be 550 bacteria in the culture after approximately 5 hours
