Front

Solve: -3 ≤ 2x - 1 ≤ 5

Back

-1 ≤ x ≤ 3

Front

What is the rate of change?

Back

The rate of change is the ratio of the change in the dependent variable to the change in the independent variable. In this case, it is -10 ft per second.

Front

Josh is thinking of two numbers. Their sum is -10 and their difference is -2. Which system of equations represents the situation?

Back

x + y = -10, x - y = -2

Front

Solve: -9x + 7 ≥ 25

Back

x ≤ -2

Front

Solve for f(5): f(5) = -x + 4

Back

f(5) = -1

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

Define a linear equation.

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

How do you solve a system of equations?

Back

You can solve a system of equations using substitution, elimination, or graphing methods.

Front

What is the difference between a function and a relation?
