P=Number of Possible Answers / Total Positive Answers - ANS-Probability Questions:
Calculate by using this fraction.
y=kx - ANS-Solve directly proportional relationships by placing into equation
Example:
A) The number of food items is directly proportional to the total money spent.
B) Work done is directly proportional to the number of workers.
B) Speed is in direct proportion to the distance (fixed time)
ax^2+bx+c=0 - ANS-Quadratic Formula allows you to calculate the solutions of any
quadratic equation.
Y-intercept - ANS-Is the point where the line crosses the y-axis, so it must be a point
that is on the y-axis. All points on the y-axis have an x-value of 0. Thus, to find the y-
intercept, you use x=0 in the equation and solve for Y. You will then have a point (0, y-
value) that is the y-intercept.
y=mx+b - ANS-is the slope-intercept form of the equation of a straight line. In the
equation y = mx + b, m is the slope of the line and b is the intercept. x and y represent
the distance of the line from the x-axis and y-axis, respectively.
Distributing negative sign outside the parenthesis - ANS-change the sign of all numbers
under a parentheses! When you distribute a negative sign outside the parentheses to all
the terms inside the parentheses, you are essentially multiplying each term by -1. This
is because a negative sign in front of a set of parentheses implies multiplication by -1.
b(m/n) - ANS-To remove a radical from an equation by squaring, you can square both
sides of the equation, raising each side to the power of the index. The square root
function is the inverse of the squaring function, so squaring both sides will cancel out
the radical.
-b/2a - ANS-X-coordinate of the vertex of a parabola. It corresponds to the position of
the symmetry axis that is defined by the graph of the quadratic formula. X = -b/2a is the
"center" of the parabola defined by a quadratic equation. Plug this in to a quadratic
formula to solve for the vertex.
