The distance Train A travels is represented by
where d is the distance in kilometers and t is the time in hours
The speed of train A is 70 kilometer per hour
To find speed of train B use the table
find out slope
The speed of train B is 75 km per hour
The speed of the train B is more
Train B is going faster
A) You would use the two points that are closest to the graphed line
(2,7) and (8,13)
B) Slope = change in Y over the change in X:
Slope = (13-7) / (8-2) = 6/6 = 1
Slope = 1
c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.
Equation is: y-7 = x-2
d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.
To isolate Y add 7 to both sides:
y = x +5
Go to 1.5 on the y axis. Then make a horizontal line that stays on that elevation from 1.5
Answer:
So I don't know the equation but I know the answer.
Length: 170 ft.
Width: 100 ft.
Step-by-step explanation:
The perimeter (The length all around) is 270. You do the perimeter divided by two and add 35, because we know they are almost equal except for one side is 35 ft. longer, That is your length. You the take the perimeter minus the length to get the width.
Equationish: P÷2= x+35= y -> P-y=w
Or: 270÷2= 135+35=170 -> 270-170= 100ft.
