Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.
I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...
-2/30 + -5/30 = -7/30
10000+4.8%=10480
10480+4.8%=10983.04
10983.04+4.8%=11510.22592
so 3 years
Yes
because
when x =2 then y = -(2) - 2 = -4
so (2,-4) is a solution
hope it helps
since numbers and letters can be repeated it should be
26 x 26 x 26 x 10 x 10 x 10 x10 = 175,760,000
