Y=mx+b
7=6(3)+b
7-18=b
b=-11
y=6x-11 (i guess that is the answer)
Answer:
6/7
Step-by-step explanation:
-3 - 4 -7 -7
---------- = -------- = ------
5 - (-1) 5 + 1 6
Do the inverse of -7/6: 6/7
Answer:
1.7 seconds
Step-by-step explanation:
we have

where
v is the initial velocity (in feet per second)
s represents the initial height (in feet)
In this problem we have
---> because the object is dropped

substitute

Remember that
When the chestnut hit the ground the value of H is equal to zero
so
For H=0

solve for t

therefore
The solution is t=1.7 sec
R=(0,2), T=(4,2)
vector:
v=(4-0,2-2)=(4,0)
v/2=(2,0)
(0,2)+v/2=(2,2)
so (2,2) is the midpoint
