4+5(6t+1) and 9+30t equivalent or not equivalent
andrezito [222]

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

A scientist counts 35 bacteria present in a culture and finds that the number of bacteria triples each hour. The function y = 35
Juliette [100K]

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
