Answer:
Depends on which place you're rounding to:
Explanation:
Rounded to the tenths place (one number after the decimal point):
x = -6.6, -9.4
Rounded to the hundredths place (two numbers after the decimal place):
x = -6.59, -9.41
Rounded to the thousandths place (three numbers after the decimal place):
x = -6.586, -9.414
I don't think you'd need to round to the ten-thousandths place. If you do lemme know and I'll edit my answer. But you should know if the next digit is 5 or greater like in 15 you'd round up. If it's less than 5, you round down.
