Algebra I Chapter 5 Test

If $A = \{1, 2, 3, 4, 5\}$ and $B = \{2, 4, 6\}$, then $A \cup B = $.

The solution set of $(x - 4)(x + 5) = 0$ is

Every point on the number line represents

If $a = 3$ and $b = -4$, which of these inequalities is true?

${\text{integers}} \cap \{\text{whole numbers}\} = \{0\}$

If $-3x < 12$, then $x < -4$.

If $(x, y) = (-3, -8)$, then the ratio of $y$ to $x$ is a number that is greater than $-2$.

$|5| - |-3| = |5 - 3|$

If a number is negative, then its opposite is positive.

Graph the solution of the inequality on the number line.
