Review Flashcard #4

Front

Which point is a solution? (0, 6), (-3, 4), (1, 0), (-4, 3)

Back

(1, 0) is a solution.

Front

Solve the inequality: -3(x + 2) < 21

Back

x > -9

Front

Solve the inequality and graph on a number line: 12 - 2x < 16

Back

x > -2

Front

Which of the following is NOT a solution to this system of inequalities? (0,-1), (0,3), (4,0), (6,-2)

Back

(0,-1) is NOT a solution.

Front

Which region of the graph represents the solution set to the system of inequalities: y ≤ \frac{1}{2}x + 2 and -y > -3x - 1?

Back

Region C represents the solution set.

Front

What is a solution to an inequality?

Back

A solution to an inequality is a value that makes the inequality true.

Front

Define a system of inequalities.

Back

A system of inequalities is a set of two or more inequalities with the same variables.

Front

What does it mean to graph an inequality?

Back

Graphing an inequality means to represent all the solutions of the inequality on a number line or coordinate plane.

Front

What is the solution set of an inequality?

Back

The solution set of an inequality is the set of all values that satisfy the inequality.

Front

How do you solve the inequality: 2x + 3 < 11?

Back

Subtract 3 from both sides: 2x < 8; then divide by 2: x < 4.
