For the first one. The complement is you subtract 90-51 = 39
The second one the supplement is 180-61= 119
The correct answer is between c and d, i hope this helps
The slope form: y = mx + b
We have:
3x - 6y - 2 = 0 |add 6y to both sides
3x - 2 = 6y |divide both sides by 6
3x/6 - 2/6 = 6y/6
x/2 - 1/3 = y
y = 1/2 x - 1/3
(8,-2). This is the correct answer because when you solve using elimination you substitute and get it
The average speed is 50 meters per second
<h3>How to determine the average speed?</h3>
The given parameters are:
Laps = 4
Time = 2 minutes
1 lap = 25 meters
Start by calculating the total distance
Distance = Laps * Meters
Distance = 4 * 25 meters
Distance = 100 meters
The average speed is then calculated as:
Speed = Distance/Time
This gives
Speed = 100 meters/2 minutes
Evaluate
Speed = 50 meters per second
Hence, the average speed is 50 meters per second
