100
This number fulfills the inequality
x > -6
x = -3
Yes/True
100
When graphing inequalities, which symbols have an OPEN circle?
< Less Than
> Greater Than
100
Describe the position of a submarine that descends 30 feet.
-30
100
Find the distance between these two points using an absolute value expression: T (-9,12) and Y (-9, -22)
Ignore the X coordinate because they are the same. Point T and Y are in different quadrants, so you add the absolute value of the Y coordinate l12l + l-22l = 34 units
200
Any number below zero is called a _______ ______
Negative number
200
The absolute value of |-30| is -30
False
200
When graphing inequalities, which inequality symbols have a CLOSED circle?
≤ : Less Than or Equal to
≥ : Greater than or Equal to
200
The temperature is 32° F at sunrise, then ascends 25° F degrees during the day. Later, it drops 13° F. What is the temperature in the evening?
44° F
200
What is the difference between location (position) and magnitude (distance) of a number?
Position tells you where the number is located on a number line, whether it si positive or negative. Magnitude is distance that number is from zero, and it is always positive.
300
Any positive or negative whole number is called an ______
Integer
300
The absolute value of |-10| is 10
True
300
Which direction do we shade for x < -3 ?
What is
Left
300
I owe $27 in debt, but then receive my $14 paycheck. How much money do I have?
$-13
300
Find the distance using an absolute value expression of the following two points: B (9, -4) and W (17,-4).
B and W are in the same quadrant because their points have the same signs. Ignore the y-coordinate becasue they are the same. Subtract the absolute value of the x-coordinates: l9l - l17l = 8 units (distance is always positive).
400
A comparison of two numbers that is not equal is called an _______
Inequality
400
If graphing x < 5, we would put an open circle on 5 and shade to the right.
False.
400
Is the following inequality graphed correctly?
x < 6
No, the graph shows x > -6
