Answer:
B) Write out the relation in an x-y table and check that each x-value corresponds to the only one x - value
thx
Step-by-step explanation:
B. A linear, partial variation
We know that speed = distance / time. From the table we have a linear function, and it's indirect, or partial.
x = 4
12/15=28/a which is a=35
then 35+28=63
14x+7=63 and x would be 4
