Describe a real-life situation in which you may want to solve a system of linear equations. What do the y-intercepts represent in your example? What does the solution (or intersection) represent in your example? If there is a food stand …
How can factoring and LCMs help make solving rational equations simpler? Provide an example. Factoring and using least common multiples can help in solving rational equations by seeing what is in the numerator and denominator and find the common parts. …

Explain the difference between finding the following two solutions: What is 15% of 50? 50 is 15% of what? This is a very good example which also could be used to illustrate the very fundamental concept of using and understanding …
Think of some real world examples in which solving or identifying algebraic expressions would be necessary or useful. Explain your examples. There could be different types of real world examples where the use of algebraic expressions might be important or …
Factoring a small number, such as 36, may be pretty simple, but how might one go about factoring a larger number, such as 19,800? Factoring a larger number seems to be difficult but can be easily possible by using various …
24. The number of lawn mower-related accidents per year, A, in a certain U.S. state can be modeled by: A=798-4t where t is the number of years since 2000. If the trend continues, in what year will the number of …
26. A line has a slope of -3 and contains the point (-2,7). Find an equation of this line. Ans. -3=(y-7)/(x-(-2) ) -3×(x+2)=y-7 -3x-6=y-7 3x+y=-6+7→3x+y=1 27. Find a line perpendicular to: 6x-4y=13+y Ans. 6x-5y=13 5y=-6x+13 y=-6/5 x+13/5 For the perpendicular …
