This means that you have to move the decimal point 4 decimal places to the left, as denoted by the negative sign. Thus, this would add 3 zeros before 5. The answer would be 0.00059.
I hope the explanation was clear to you. Have a good day.
Add the exponents if the bases are the same, multiply the bases if the exponents are the same, if nothing is the same just solve it.
This is the answer...
y=250-25x
y=30+30x
If r=-3, then it would be -3-12 which equals -15
