Answer:
(-67/3, -13/3)
Step-by-step explanation:
Answer:
Coordinate of E:(-2,3) Coordinate of G: (2.5,1.5)
Parallel: slopes both = -1/3
1/2 segment: EG length= 3 BC length=6: This is the only one I'm not sure about.
I will show the work for both the problems down below.
Step-by-step explanation:
Finding coordinates:
1+(-5)/2=-2 5+1/2=3
(-2,3)
1+4/2= 2.5 5+(-2)/2= 1.5
(2.5,1.5)
Show work verifying the EG and BC are parallel:
You can do this by finding the slope
Slop formula (y2-y1)/(x2-x1)
(1.5-3)/(2.5-(-2))
Then simplify
-1.5/2/5= -1/3 which i your slope. You use the same formula and follow thee same steps for the points of BC and both will come up as -1/4 meaning they are parallel.
Show work verifying that EG and BC are parallel:
Use distance formula to find how long each line is
√(x2-x1)^2+(y2-y1)^2
√(2.5-(-2)^2)+(1.5-3)^2
Simplify
√4.5+(1.5)=3
Do the same thing with BC and you will get 6
Answer:
Solve one of the equations for y, take that answer and plug into the second equation in place of y. Then solve for x.
Step-by-step explanation:
Need equations if you want actual answer
Answer:
21 miles per gallon
Step-by-step explanation:
The formula for slope is
Using the points (0, 0) and (1, 21), we have
m = (21-0)/(1-0) = 21/1 = 21
This means they get 21 miles per gallon of gas.
The snail will crawl 800cm in 2 hours
4m*2h=8h
8h*100=800cm
