Consider the plot created from the residuals of a line of best fit for a set of data.
does the residual plot show that the line of best fit is appropriate for the data?
yes, the points have no pattern.
no, the points are evenly distributed about the x-axis.
no, the points are in a linear pattern.
yes, the points are in a curved pattern.

Which graph shows a function with a range of all real numbers greater than or equal to -1

What is the solution to the system of equations? (–2, –8) (–1, –5) (0, –2) (2, 4)

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.
