how to find domain with a given equation - Correct Answer- -if a fraction, set denom. to zero,
then solve
-in equation, plug in 0 for x
*usually can be a + or - solution*
(-) + (-)= ...
(-) x (-)= ...
(-) divided by a (-)= ... - Correct Answer- (-)
(+)
(+)
quotient - Correct Answer- division
adding and subtracting fractions - Correct Answer- -make denoms the same
-add/subtract numerators
multiplying fractions - Correct Answer- just multiply numerators across and denoms across
and simplify
dividing fraction - Correct Answer- multiply by reciprocal (change second fraction to
reciprocal)
multiplying/dividing/adding mixed fractions - Correct Answer- turn them into regular
fractions (multiplying # by denom, adding it to num, keeping denom the same) and continue

set up as if you're subtracting two large numbers (on top and on bottom)
, how to solve problems like 5-2 (1/3) - Correct Answer- 1) make problem 5- (2 (1/3))
2) separate : 5- 2- (1/3) to get: 3- (1/3)
3) rewrite whole #: 2+1- (1/3)
4) rewrite as: 2 + (3/3) - (1/3) to ed up with:
2 (2/3)
inequality problem rule (<, >, etc like problems) - Correct Answer- When
*multiplying/dividing* each side by a *positive* number, the inequality sign *stays the
same*
When *multiplying/dividing* each side by a *negative* number, we *flip* the inequality
sign.

distance formula - Correct Answer- d= rate x time
percent to fraction - Correct Answer- percent as numerator and 100 as denominator, then
simplify
fraction to percent - Correct Answer- 1) do long division with denom as outside and
numerator as inside
2) move decimal over 2 places to make it into a %
