-4K-7+5k
First. You have to plus the negative 4K in the 5K together which makes it K or
1K
So now you equation would be: k-7
<u>Answer:</u>
It will take 2 hours 36 minutes for the two trains to meet.
<u>Step-by-step explanation:</u>
The distance between the two trains is decreasing by 
miles per hour, which can be written as 
.
So at this rate, the distance between the trains will be reduced to zero in:
Changing 2.6 hours to hours and minutes:
Therefore, it will take 2 hours 36 minutes for the two trains to meet.
Step 1: Add 3x to both sides to get 4 = 3x - 1
Step 2: Add 1 to both sides to get 5 = 3x
Step 3: Divide by 3 on both sides to get 5/3 = x
Answer:
-8

14. The equation would be -16t^2+60t+7 To find the maximum point plug in values into the equation -b/2a to find the axis of symmetry, and plug that number in for t.
b=60, a=-16
-60/-32=t=1.875
-16(1.875)^2+60(1.875)+7=63.25
Maximum point: (1.875,63.25)
The ball will land after about 3.86 seconds
