Answer:
y =
Step-by-step explanation:
Given
y = 3xy - 1
Collect terms in y on the left side by subtracting 3xy from both sides
y - 3xy = - 1 ← factor out y on the left side
y(1 - 3x) = - 1 ( divide both sides by 1 - 3x
y = ← multiply numerator/denominator by - 1
y =
Answer:
20 seconds
Step-by-step explanation:
Your friend starts 10 meters in front of the starting line.
You start from the starting line.
You run at 6 meters/ second.
Your friend runs at 5.5 meters/second.
You and your friend will be at the same distance from the starting line only when you are able to catch your friend.
The relative speed between you two is the difference in your speed and your friend's speed that is:
So to cover 10 meters of separation at the speed of 0.5 meter/second it will take:
So it will take 20 seconds for you and your friend to be at the same distance from the starting line.
The first one is true
if the angles of a right triangle are 90,45,45
the legs are equal. so if AC is 13, Back will be 13, too.
now you can get help from Pythagoras theorem :
good luck
