Exponents and Powers. An expression like 2 3 is called a power 2 3 = 2 2 2 = 8 This expression is read as “two to the third power” or “two cubed” The repeated factor is the base The exponent indicates how many times the base is used as a factorBy lyre
Distance Formula and Midpoint Formula. Distance Formula. The distance formula is derived from the Pythagorean theorem c 2 = a 2 + b 2 . Substituting d for c, for a, a nd for b in the Pythagorean equation, you get. d.By nixie
3.4 Absolute Value Functions. Absolute Value is defined by:. The graph of this piecewise function consists of 2 rays, is V-shaped and opens up. To the left of x=0 the line is y = -x. To the right of x = 0 the line is y = x. Notice that the graph is symmetric in the y-axis becauseBy gefen

Absolute Value. – 5. – 4. – 3. – 2. – 1. 0. 1. 2. 3. 4. 5. Symbol for absolute value. Distance of 4. Distance of 5. The absolute value of a real number a , denoted by | a |, is the distance between a and 0 on the number line. | – 4| = 4. |5| = 5. Example.
Absolute Value. Plot the following points and its opposite number on the number line:. -7 5 6 -2 8 -4 . Vocabulary. Absolute Value- the number’s distance from 0 on the number line.
ABSOLUTE VALUE. For each value, write it opposite, then its absolute value. Watch this:. http://virtualnerd.com/middle-math/integers-coordinate-plane/integers-absolute-value/calculate-absolue-value. opposite absolute value. -3 +3 3 4 -4 4 15 -15 15
Absolute Value. By: Katie Harbeck, Huy Nguyen, Myle Nguyen, Julie Pham. Welcome to the absolute value lesson. The equation of absolute value is Y=a|x - h| + k A represents slope X is the independent variable H is the X value of the vertex K is the Y value of the vertex. Example:.
Absolute Value. Just how far from zero are you?. What are opposites on a number line?. Two numbers that are the same distance from zero are said to be opposites. Graph the integer set from –5 to + 5. But what is Absolute Value?.
Absolute Value. Math Aero Standards- 5, Level -5 I can understand Absolute value. HW Write down your Science topic. Review. Integers Number Line. Be positive. I have a terrible haircut The pollution level in Shanghai is 600 My teachers give me so much HW
Absolute Value. Objective: To find the opposite and the absolute value of an integer. Opposites. Two numbers are opposites of one another if they are represented by points that are the same distance from 0, but on opposite sides of 0. The number line below shows that -4 and +4 are opposites.
Absolute Value. 2-1-2. Distance. A distance is never zero. Number line. How far is 3 from zero? How far is -3 from zero?. |x| the absolute value of x. |3| asks how far from zero is 3? |-5| asks how far from zero is -5?. Absolute Value. Always gives a positive answer.
Absolute Value. -7. -2. -1. 1. 3. 5. 7. -6. -5. -4. -3. 0. 4. 6. 8. 2. 1 block. 1 block. You walk directly east from your house one block. How far from your house are you?. You walk directly west from your house one block. How far from your house are you?.
Absolute Value. Distance from zero on a number line. Absolute Value. 5 = 5. -5 = 5. The absolute value of 5 is 5. The absolute value of -5 is 5. Absolute Value. The distance away from zero. -4 = 4. 2 = 2. 4 steps to 0. 2 steps to 0. -4. -2. 0. 2. 4. Absolute Value.
