Zero pairs are generated by combining the EQUAL number of positive and negative numbers .
A zero pair could be -11 + 11
A^3-19 should be the answer, good luck
So, our starting point, at zero hours, you already owe ten dollars.
So far you know it is +10.
Now, you multiply for by however many hours you have rented the bike for.
So the equation is:
4x+10.
x= # of hours bike is rented for.
Hope this helps! Have a happy holiday!
