1)The SPEED of an object tells us how fast this object is moving, bit it doesn't indicate the direction of :
Speed = distance/time
2) The VELOVITY of an object tells us how fast this object is moving and in which direction it's moving ( If UP, then it's positive. If DOWN, then it's negative. Same logic for moving right (+) or left (opposite to right, then -)
Velocity = distance/time
In short te absolute value of Velocity = Value of speed:
| Velocity | = Speed
This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3
Answer:
1. More magnets are longer than 2 1/2
2. 10 magnets measure in whole numbers and 5 magnets between 2 whole numbers
3. Because the shortest magnet is 1 inch and the longest magnet is 4 inches.
Step-by-step explanation:
1. There are 7 magnets that are longer than 7 1/2 and only 6 magnets that are shorter than 2 1/2. (The 2 magnets that are exactly 2 1/2 are neither longer nor shorter therefore they do not apply to the question.)
F(x)=x^2+3x-7, x=3
f(3)=3^2+3(3)-7
f(3)=9+9-7
f(3)=11
Answer:
X=11
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
3x−5−2x=2x+6−2x
x−5=6
Step 2: Add 5 to both sides.
x−5+5=6+5
x=11
