What is n inequality? Where would you use them in the real world?

A inequality is used to determine the best solution to a problem. This solution could be as simple as determining how many of a product should be produced to maximize a profit or as complicated as determining the correct combination of drugs to give a patient.

Step-by-step explanation:

An inequality is a comparison of two values, showing if one is less than, greater than, or equal to one another.

Inequalities could be used in the real world to compare many things, for example in business, you would or could use an inequality to compare your income to your expenses. (Income (<, >, or ≤, ≥) Expenses)

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
