Chapter 5: Problem 88

How do you determine if an ordered pair is a solution of an inequality in two variables, \(x\) and \(y ?\)

Short Answer

Expert verified
To check if an ordered pair is a solution to an inequality in two variables \(x\) and \(y\), one should substitute the values of the ordered pair in place of \(x\) and \(y\) in the inequality, and then verify if the inequality holds true. If it does, the ordered pair is a solution. If it doesn't, it is not a solution.

Step by step solution

01

Understand the Inequality

Begin with understanding the given inequality with two variables, \(x\) and \(y\). Ensure that the inequality is in a suitable form for easy substitution, for instance, standard form or slope-intercept form.
02

Obtain the Ordered Pair

Identify the ordered pair you need to verify. Ordered pairs are given in the format (x,y), where the first value represents the value of \(x\) and the second value is the value of \(y\).
03

Substitution

Substitute the ordered pair's values into the inequality for corresponding variable. Replace \(x\) with the first value of the ordered pair and \(y\) with the second value.
04

Verify the Inequality

After substituting the values, solve any arithmetic that is required and then verify if the inequality is true or not. If the inequality holds, then the ordered pair is an solution to the inequality. If it does not hold, then the ordered pair is not a solution of the inequality.

A person invested 17,000 dollar for one year, part at 10%, part at 12%, and the remainder at 15%.The total annual income from these investments was 2110 dollar . The amount of money invested at 12% was 1000 dollar less than the amount invested at 10% and 15% combined. Find the amount invested at each rate.

determine whether each statement makes sense or does not make sense, and explain your reasoning. I apply partial fraction decompositions for rational expressions of the form \(\frac{P(x)}{Q(x)},\) where \(P\) and \(Q\) have no common factors and the degree of \(P\) is greater than the degree of \(Q .\)

write the partial fraction decomposition of each rational expression. $$ \frac{a x+b}{(x-c)^{2}} \quad(c \neq 0) $$

Suppose that you inherit 10,000 dollar. The will states how you must invest the money. Some (or all) of the money must be invested in stocks and bonds. The requirements are that at least 3000 dollar be invested in bonds, with expected returns of 0.08 dollar per dollar, and at least 2000 dollar be invested in stocks, with expected returns of 0.12 dollar per dollar. Because the stocks are medium risk, the final stipulation requires that the investment in bonds should never be less than the investment in stocks. How should the money be invested so as to maximize your expected returns?
