Answer:
A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if: y = k x. for some constant k , called the constant of proportionality .
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:
8.5
Step-by-step explanation:
to do this you would multiply 2.125 or 2 1/8 by 4
Answer:
1. the length of the missing side is 45ft
2. the wall paper needed to go around all six wall is 210ft
Step-by-step explanation:
1/5 * 4 2/3.....turn mixed number to improper fraction
1/5 * 14/3 = (1 * 14) / (5 * 3) =
14/15 <==
