Find the domain of the rational expression: 4-x/3x+21

(4-x) /(3x+21)

The denominator cannot be zero

3x + 21 ≠ 0

3x ≠ -21

x ≠ -7

The domain of the function will be all real number except -7

{x | x ≠ -7}

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
