Chapters 5-6 Finals Review Algebra 1

Front

What is the solution to the inequality -x / 5 > -20?

Back

x < 100

Front

Solve by graphing: y = x + 2 and y = -2x - 7. What is the solution as an ordered pair (x,y)?

Back

(-3,-1)

Front

Solve the inequality 77 ≤ 5 + 8n. What is the solution?

Back

n ≥ 9

Front

Write an inequality for the graph that shows x ≤ -2 OR x > 5.

Back

x ≤ -2 OR x > 5

Front

For the function y < 2x + 3, what type of line and shading is represented?

Back

The line would be dashed with shading below.

Front

What does it mean when an inequality is represented with a dashed line?

Back

It means that the points on the line are not included in the solution.

Front

How do you graph the inequality y > 3?

Back

Draw a dashed horizontal line at y = 3 and shade above the line.

Front

What is the difference between 'AND' and 'OR' in compound inequalities?

Back

'AND' means both conditions must be true; 'OR' means at least one condition must be true.

Front

What is the solution set for the inequality 2x + 3 < 7?

Back

x < 2.

Front

How do you solve the inequality 4n - 5 > 3?

Back

n > 2.
