The correct answer would be more than 10; 15x > 40+11x
-11 from each side
4x > 40
Divide by 4 on each side
x > 10
Therefore there must be more than 10 tables for the second option to be cheaper.
Notice the dependent and independent variables. X axis is usually the independent while y is the dependent. The dependent variable is affected by the independent one. Ravi is driving at a constant speed, which one looks like it is not changing in any direction whatsoever? But, Ravi is speeding up, so which one is adding the speeding (moving up) part of Ravi's driving? And finally, what graph also showcases the visual of Ravi slowing down after he was driving at a constant speed and then speeding up (hint: straight, up, down)?

Answer:
3. about 7.48 hours
4. about 1.8892 hours
Step-by-step explanation:
Both of these questions make use of the relation ...
time = distance / speed
3. time = (965 mi)/(129 mi/h) ≈ 7.48062 h ≈ 7.48 h
__
4. time = (612.1 mi)/(324 mi/h) ≈ 1.889198 h ≈ 1.8892 h
(We have rounded the time to sufficient precision so that the distance at the given speed rounds to the number given.)
