Grade 9 Math Exam-Graded A
simplifying - correct answer-write the numerator and denominator as a product of
factors, then erase common factors and you will get the result.
converting mixed numbers - correct answer-multiply denominator by the whole number
and add the numerator
to multiply fractions... - correct answer-just multiply the top and bottom to get the new
fraction, then simplify
to divide fractions... - correct answer-multiply the second ones reciprocal and then
simplify
adding/ subtracting fractions... - correct answer-find the common denominator and then
add/subtract
independent - correct answer-relies on nothing
dependent - correct answer-relies on independent
outliers - correct answer-is different then then rest of the data
power - correct answer-a product of identical factors and there is 2 parts a base and a
exponent
base - correct answer-identical factor
exponent - correct answer-how many bases is multiplied
odd number of negative factors= - correct answer-negative answer
even number of negative factors= - correct answer-positive answer
product law - correct answer-when multiplying powers with the same base, add the
exponents to write the product as a single power
quotient law - correct answer-when dividing powers with the same base, subtract the
exponents to write the quotient as a single power
exponent of 0 - correct answer-gives a answer of 1
, exponent of 1 - correct answer-gives the same number
power of a power law - correct answer-a power can be written as a single power by
multiplying the exponents
exponents with fractional base law - correct answer-if there is a exponents on a fraction
then you have to give the exponent to both the numerator and denominator
mono - correct answer-1
bi - correct answer-2
tri - correct answer-3
degree of term - correct answer-sum of the exponents
degree of polynominal - correct answer-degree of highest term
coefficient - correct answer-the multiplier placed immediately before the variable in a
term
like terms - correct answer-terms that have the same variable and the same exponent
term - correct answer-one quantity in an algebraic expression
when multiplying or dividing algebraic expressions - correct answer-multiply/divide
number by number and variable by variable
like terms have - correct answer-identical variables (count the exponents with the
variable)
to add polynomials - correct answer-remove bracket and collect like terms
to subtract polynomials - correct answer-add the opposite polynomials
whatever is outside bracket - correct answer-multiply it with whats inside the bracket
with addition or subtraction, there are only 2 possibilities when removing brackets -
correct answer-1) if there is no sign before the bracket or a plus sign, then simply drop
the brackets and everything is the same
2)if there is a subtraction sign before the bracket and the sign of every thing inside, is
the opposite
when distributing - correct answer-multiply the monominal by each term in the
polynomial, multiply numerical coefficient, apply exponents laws,
