Answer:
They can never be both either increasing or decreasing.
Step-by-step explanation:
If the rate of change i.e. the slope of one linear function is positive, that means the graph of the linear function makes angle which varies between 0° to 90° with respect to the positive direction of the x-axis.
Therefore, the function must be increasing.
Again, if the rate of change i.e. the slope of one linear function is negative, that means the graph of the linear function makes angle which varies between 90° to 180° with respect to the positive direction of the x-axis.
Therefore, the function must be decreasing.
Hence, if the rate of change of one linear function is positive and for another is negative, they can never be both either increasing or decreasing. (Answer)

Answer:
60% of the students passed the test
Step-by-step explanation:
total # of people taking the test: 36
# of people passed: 18
# of people failed: 36-18 = 18 (18 people failed the test)
percentage= (number of favorable outcomes/total number of outcomes)* 100%
(18/36)*100
= 60%
