(1/2)x+b=y because the equation that given the slope is 1/2 if you leave y alone and take the x’s number
put the point now , 4+b=3 so b is -1
the equation is (1/2)x-1=y
Is 20 and answer because I did this on a calculator and this is the only one to me that would make since
I think group 1 if it is wrong then write is comment box
Answer: 2.11 s
Step-by-step explanation:
Given
Equation of rockets height is given by

Height will be zero once the rocket lands on the ground
So, we can write
Average speed = (distance covered in some time) / (time to cover the distance)
4 hours 45 minutes = 4-3/4 hours = 4.75 hours
Average speed = (3,800 km) / (4.75 hours) = 800 km/hr
