Expressions and Equations
NC.8.EE.1 Develop and apply the properties of integer exponents to generate equivalent numerical expressions.
|
|
|
NC.8.EE.2 Use square root and cube root symbols to:
|
|
|
NC.8.EE.2.a Represent solutions to equations of the form x² = p and x³ = p, where p is a positive
rational number.
|
|
|
NC.8.EE.2.b Evaluate square roots of perfect squares and cube roots of perfect cubes for positive
numbers less than or equal to 400.
|
|
|
NC.8.EE.3 Use numbers expressed in scientific notation to estimate very large or very small quantities and to express how many times as much one is than the other.
|
|
|
NC.8.EE.4 Perform multiplication and division with numbers expressed in scientific notation to solve real-world problems, including problems where both decimal and scientific notation are used.
|
|
|
NC.8.EE.7 Solve real-world and mathematical problems by writing and solving equations and inequalities in one variable.
|
|
|
NC.8.EE.7.a Recognize linear equations in one variable as having one solution, infinitely many
solutions, or no solutions.
|
|
|
NC.8.EE.7.b Solve linear equations and inequalities including multi-step equations and inequalities
with the same variable on both sides.
|
|
|
NC.8.EE.8 Analyze and solve a system of two linear equations in two variables in slope-intercept form.
|
|
|
NC.8.EE.8.a Understand that solutions to a system of two linear equations correspond to the
points of intersection of their graphs because the point of intersection satisfies both equations
simultaneously.
|
|
|
NC.8.EE.8.b Solve real-world and mathematical problems leading to systems of linear equations
by graphing the equations. Solve simple cases by inspection.
|
|
|
Functions
NC.8.F.1 Understand that a function is a rule that assigns to each input exactly one output.
|
|
|
NC.8.F.1.a Recognize functions when graphed as the set of ordered pairs consisting of an input
and exactly one corresponding output.
|
|
|
NC.8.F.1.b Recognize functions given a table of values or a set of ordered pairs.
