ALEKS EXAM
what is absolute value? distance from zero on a number line
if you get a negative absolute value, why is it said to not because distance can't be negative
have a solution?
what are integers? all whole negative and positive numbers
when should u switch the sign on an inequality? when you're dividing or multiplying by a negative number
why is it that you can have a both negative and positive because if your main solution is positive, if u plug that back into the absolute
solution for absolute value? value bars, you'll still get a positive number. absolute value always has to be
positive, so if you get a negative number its not the absolute value. remember
this numbers that u get are the result, not the ones u plug in
what to do when vertical shifting a graph? take what's in the parentheses and put it equal to 0, then translate left or right
that exact amount
when you get 0=0 as the solution to an expression, what all real numbers are solutions, because a real number equals a real number
does this mean?
when you get 0=-3 as the solution, what does this mean? there's no solution
a pair of coordinates represent a function if what? they don't have the same x-coordinates
if you have a negative exponent as a denominator and move the negative exponent to the numerator and make it positive
one as the numerator, what rule can you follow to make
the numerator positive?
when using elimination, what is the first step you have to isolate one of the variables,you can do this by multiplying both equations by
do? different variables because they're not equal to each other, so you can do that
and once its all in order just add down
what is the formula for volume of a cylinder? V=pi r squared h
what units is volume always in? cubed
how do u find the perfect square term? take half of the coefficient term, then square it
what's something to keep in mind when you're you have to multiply both sides of the LCD even if one side already has it,
determining the LCD for one fraction on one side of the because they're equal to each other
equation and one on the other?
what should u remember when solving an absolute value if the solution to the equation is bigger than 0, then you split them up and
equation that is different from an absolute value consider both solutions, if the solution is already less than 0, it has no solutions
inequality? because its already negative
, ALEKS EXAM
the difference between finding a union of a set and the set of all elements that are in set a or set b for union, set of all elements that are
intersection of a set? in set a and set b for intersection
what is a rational number? a ratio of two integers, also fractions and squares that equal integers
what is formula for area of a semicircle a=1/2r^2
what is formula for area of a triangle 1/2bh
what do u do to find the roots? get the expression into quadratic form, get solutions and set equal to 0
what happens if you dont get the two identical binomials either try grouping them differently or it cant be factored by grouping
by grouping?
whats one thing u should add in when doing grouping? if you have to factor by 1 to get the identical binomial, then you have to add a +1
what is the formula for circumference of a circle? C= pi x d
what is an LCM? its exactly like the least common denominator but without the fraction
what's the first step to solving a quadratic equation foil and get everything on one side, then make it equal 0
needing simplification?
what is the distance formula? square root of (x2-x1)^2 + (y2-y1)^2
with absolute value inequalities, do you still have to split yes
them up if the value is greater than 0?
