Answer:


Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
Let
s ----> the speed in units per second
d ---> the distance in units
t ---> is the time in seconds
BUG A
we have


The speed is equal to

substitute

If x is the point reached by A after t seconds
then
Multiply the speed by the time


BUG B
we have


The speed is equal to

substitute

If y is the point reached by B after t seconds
then
Multiply the speed by the time

----> is negative because B is moving in the negative direction
Answer:
Step-by-step explanation:
-√96 = -4√6
The volume of the marbles is 26-20.9 = 5.1 l and there ar e85 marbles
5.1/85 = .06 l/marble
then 200 marbles would requrie .06 l/marble x 200 marbles = 12 liters
so he would only need 26-12= 14 liters of water to fill the tank !
The slope is the change in Y over the change inX: Using the two points given: (3,9) and (1,3)
The slope is (9-3) / (3-1)
Slope = 6 / 2
Slope = 3
The answer is A.
