Step-by-step explanation:
in inequality, the word at least means that is equal or more than. so that means that Allie might equal or more than 50 hours in the model but if you're to solve it, Allie will need 30 or more hours. and since she already has 20, add the 20.
When the function goes 1 to the right, it goes 2 down. Therefore the direction of the function is

Hence, the function represented is
y = -2x
12.
It is easy all you have to do is 15-3 because 1+2=3
