In a lab, a scientist is growing bacteria for a study. The scientist begins with a bacteria population of b cells. She discovers that after 2 hours, the population of bacteria is

62 cells. If the population of the bacteria after these 2 hours is one million cells, what

was the population at the start? Explain how you found your answer.

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
