Answer:
The statement means that after 2 hours, there are 90 bacteria in the culture.
Step-by-step explanation:
The number of bacteria after x hours is given by the function states in the exercise. We have that f(x) will be the number of bacteria after x hours.
Which statement best describes the meaning of the equation f(2) = 90 ?
The statement means that after 2 hours, there are 90 bacteria in the culture.
Answer:
Hence, the equation is proportional.
Step-by-step explanation:
To test for proportionality ;
y = 12x
For a proportional relationship ;
y α x
y = kx ; where, k is the constant of proportionality.
From. The equation given
y = 12x ; 12 is thw proportionality constant.
B because 14-5=9 and 9-8= 1

+ 474 equals
483.
First, multiply 3 two (3x3) times to get 9. Your problem should look like: 9 + 474.
Second, add 9 + 474 to get 483, which is the correct answer.
