If (x,y) is reflected across the x axis, it becomes (x,-y)
so
(-4,2)
times -1 to y
(-4,-2)
A' is (-4,-2)
The length is 15 feet.
Write them both as ratios!
6/10=9/x
6x=90
x=15
Answer:
C. or 54
Step-by-step explanation:
Assuming we are trying to find r then you would get 3*44 because distance=speed*time so distance is for the 3 hour time is 132 miles. To find the reaming distance you do 240-132= 108 so then we know distance/time=speed so 108/2=54 so the speed is 54 mph
