MATH 60 EXAM 3 REVIEW (Chapters 7 and 8)
... After the semester is over, Herman discovers that the math department has changed textbooks (again) so the bookstore won't buy back his nearly-new book. Herman goes to the roof of the math building, which is 160 feet high, and chucks his book straight down at 48 feet per second. How many seconds doe ...

Test also includes review problems from earlier sections so study
... NOTE: The equations in Problems 60 – 70 are quadratic equations, which means they can be written in the form ax2 + bx + c = 0 where a ≠ 0. To solve them, simplify each side of the equation if possible, then move all terms to one side of the equation so that one side equals zero, and then solve using ...

GRAPHING LINEAR EQUATIONS IN TWO VARIABLES
... To graph a linear inequality with two variables it is probably easier and recommended to change it to slope intercept form. There are two important rules to remember when graphing a linear inequality. If the inequality sign is > or <, the line is dashed. If the inequality is ≥ or ≤ , then the line i ...

9.1.1 Simplify Rational Expressions
... 9.3.2 Add and subtract rational expressions that do not have a common denominator. Steps to add and subtract algebraic fractions: 1. Factor the denominators and find the LCD. Then rewrite each fraction in terms of the LCD. 2. Add (and/or subtract) the numerators. The denominator is the LCD. 3. Simpl ...

Solving equations using logs
... Solving equations using logs mc-logs4-2009-1 We can use logarithms to solve equations where the unknown is in the power as in, for example, 4x = 15. Whilst logarithms to any base can be used, it is common practice to use base 10, as these are readily available on your calculator. ...

Or then again, λ = 0 gives x = 30, y = 16 and z = 0, so this is another possible solution. Exercise. Use Gaussian elimination to solve 2x ...

... before you had $512? You could solve this problem if you could solve 2x = 8 by using an inverse operation that undoes raising a base to an exponent equation to model this situation. This operation is called finding the logarithm. A logarithm is the exponent to which a specified base is raised to obt ...
