The two trains the same distance from Buffalo is 20
Answer:
I get x = 16/7 ft or about 2.29 ft for the width and 4.29 ft for the height.
Step-by-step explanation:
To find f(-20), first figure out which piece x = -20 fits with.
Since -20 < -12, x = -20 first in the domain used by the third piece.
For f(-20), treat this function as if it was just f(x) = 3x-7.
f(-20) = 3(-20) -7
= -60 - 7
= -67
