ALEKS UPDATED QUESTIONS AND VERIFIED
SOLUTIONS
◉ graph >, <
Answer: DOTTED line
◉ every, each, per (writing equations)
Answer: rate/ set y value equal to (multiply this value by the x
variable)
◉ When writing an equation or working ANY inequality problem
what does it help to do first?
Answer: write out what's happening
◉ What should you double check for EVERY time
Answer: writing problem down wrong (NEGATIVE SIGNS),
uncarried negative signs, unflipped inequality signs, undotted lines,
incorrect multiplication, fully simplified
◉ distance =
Answer: rate x time
,◉ When solving a system of equations can you add the equations
together if one of the variables will cancel out?
Answer: YES
◉ What should you always write out when doing your work?
Answer: Fraction conversions, simplification steps, line graphs
(interval notation)
◉ What standard does an equation/ graph have to meet to be
considered a function?
Answer: Each input can only have one output
◉ How do you translate a graph up or down?
Answer: The value outside of the parentheses (DONT change sign)
◉ How do you translate a graph side to side?
Answer: The value inside the parentheses (CHANGE SIGN)
◉ Translate -(x + 3)^3 - 2 from -x^3
Answer: left 3, down 2
◉ When translating do you need to solve the equation?
, Answer: No, just look at the numbers inside (side to side change
sign) and outside (up and down DONT change sign) the parentheses
◉ What is the domain?
Answer: The x limits
◉ What is the range?
Answer: The y limits
◉ U represents
Answer: Numbers in EITHER set (Union)
◉ ⋂ represents
Answer: Numbers in BOTH sets (Intersection)
◉ What is the quadratic formula?
Answer: -b±√b^2-4ac/2a
◉ When asked for the rate, should you give the rate or the rate times
the time?
Answer: THE RATE
