What do you mean by group these numbers
Answer:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear.
36x-8y^2
36(3)-8(-6)^2
108-8(36)

Answer:
v = 85/t
Step-by-step explanation:
Velocity is the change in displacement of a body with respect to time. It is expressed as
velocity = displacement/time
v = d/t
Given
d = 85km
t = t
Substitute tis parameters into the function;
v = 85/t
Hence the velocity v as a function of travel time t in hours is expressed as;
v = 85/t
