20 because if you subtract 32 from 12 you get 20 and now you would want to work on 2/4 minus 1/2 since they are the same 2/4 =1/2 simplified you get 0 which leaves your answer to just 20
plz mark brainliest please and thank you and if i helped please leave a 5 stars rating and a thank you
Answer:
15 students per month
Step-by-step explanation:
The rate of change is calculated as
f(b) = 95 ← number of students in October
f(a) = 65 ← number of students in August
b - a = 2 ← difference in months
Thus
rate of change = = = 15
A proportional relationship can we written as follows:-
y = mx
Where 'y' is dependent variable, 'x' is independent variable, and 'm' is the slope or we can say 'm' is constant of proportionality.
'm' can take any value whether negative or positive, decimal or whole number. 'm' is a real number.
The given problem is y = x/9 and student says we can only multiply constant, and not divide. We disagree with this comment because m= 1/9 is correct.
So y = 1/9 x makes sense.
y = x/9 represents a proportional relationship.
