Answer:
slope:
m= (y2-y1)/(x2-x1)
you just take two points and plug in the x and y values into the equation above
Step-by-step explanation:
Answer
The zero or roots would be x= -6
Step-by-step explanation:
It’s b because you simplify it to it’s simplest form
Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
You want to find the resultant of ...
3 cis 0° +20 cis 20° = (3, 0) +(18.794, 6.840) = (21.794, 6.840)
The magnitude is the root of the sum of the squares of the velocities in the horizontal and vertical directions:
s = √(21.794² +6.840²) ≈ 22.8
The direction is found from the fact that the tangent of the angle is the ratio of vertical to horizontal coordinates:
angle = arctan(6.840/21.794) ≈ 17.4°
The resultant velocity is 22.8∠17.4° meters per second.
4x+20=5y
Divide 5 on both sides
so your answer would be
4/5x+4=y
x+15=3y
Divide 3 on both sides
so your answer would be
3x+5=y
