QUESTIONS WITH CORRECT
ANSWERS
Dividing Fractions - Answer-Invert (reciprocal) the second fraction and multiply. flip the
second guy and multiply
common factor - Answer-A number that is a factor of two or more numbers
prime factor - Answer-A factor of a number that is also a prime number.
ex. factors of 6 are 1,2,3,6 and 2/3 are prime
greatest common factor (GCF) - Answer-The largest factor that two or more numbers
have in common.
least common multiple (LCM) - Answer-The smallest multiple (other than zero) that two
or more numbers have in common.
proportion - Answer-1. The relationship of one thing to another in size, amount, etc. 2.
Size or weight relationships among structures or among elements in a single structure.
direct proportion - Answer-a relationship between two variables in which their ratio is
constant
inverse proportion - Answer-a relation between two quantities such that one increases
in proportion as the other decreases.
ratio - Answer-a comparison of two quantities in a particular order
for example, 14 computers and 20 students
the ratio is 20:14 then 10:7
constant of proportionality - Answer-the constant ratio in a proportional linear
relationship
slope formula - Answer-(y₂- y₁) / (x₂- x₁)
slope - Answer-The steepness of a line on a graph
, coordinates - Answer-Ordered pairs that identify points on a coordinate plane. (x,y)
relation - Answer-a set of pairs of input and output values. there is not a unique y or x
value for each point
function - Answer-a relation in which each element of the domain is paired with exactly
one element of the range. One x for one Y
Monomial - Answer-an expression with only one term
standard form - Answer-Ax+By=C
slope-intercept form - Answer-y=mx+b
point slope form - Answer-y-y1=m(x-x1)
two-point form - Answer-y-y₁=(y₂-y₁)/(x₂-x₁)×(x-x₁)
intercept form - Answer-x/x1+y/y1=1
solution set - Answer-The set of all values of the variable that make the equation true.
empty set - Answer-a set containing no elements
equivalent equations - Answer-Two or more equations with the same solution
identity - Answer-a term whose value or determinent is equal to 1
quadratic function - Answer-A function that can be written in the form f(x) = ax2+bx+c,
where a,b,and c are real numbers and a ≠ 0
Quadratic Formula - Answer-x = -b ± √(b² - 4ac)/2a
square root function - Answer-is a function that contains a radical and can be written as
f(x)=squareroot(ax+b)
absolute value function - Answer-f(x)=|ax+b|
exponential function - Answer-y=ab^x
logarithmic function - Answer-a function of the form f(x)=logbX, where b≠1 and b>0,
which is the inverse of the exponential function f(x)=b^X
Substitution - Answer-An algebraic model that can be used to find the exact solution of
a system of equations by subbing in the easier equation into the more complex one
