Karima, Brenda, Xavier, and Jody are looking for ratios which are equivalent to 4:8 in the columns of the multiplication table below. A multiplication table.

Karima says that only the numbers in columns 4 and 8 form equivalent ratios for 4:8.

Brenda says that only Karima’s ratios and the numbers in columns 2 and 4 form equivalent ratios for 4:8.

Xavier says that Karima’s ratios, Brenda’s ratios, and the numbers in columns 1 and 2 form equivalent ratios for 4:8.

Jody says that any pair of columns with even numbers forms equivalent ratios for 4:8.

Who is correct?
Karima
Brenda
Xavier
Jody

Solve |2x - 5| = 4 if anyone could , that would be great

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
