Y=mx+b
6x+2y=-88
2y=-88-6x
y=-44-3x
y=-3x-44
m is the slope
b is the y-intercept
1 1/3 - 5/6
Find common demoninator which is 6.
Then do 2*1=2.
Now you got 2/6 - 5/6 = -3/6
Simplify:
-3/6=-1/2
Then combined answers.
1 - 1/2 = 1/2
Final answer is 1/2
H=-5(t^2 - 16t)
H=-5(t^2 - 16t +64)+320
H=-5(t-8)^2 +320
Vertex is at (8, 320)
The max height is 320 m.
If he travels 12km/h for 3 hours then he went 36km in 3hr. The answer is 36km.
