Answer:
x>= -46/9 (x greater than or equal to -46/9)
Explanation:
when translating the question, at most means that it is less than or equal to the value being named, therefore the equation is 9x+21<= -25
to begin solving we subtract 21 from both sides and get 9x<=-46
then when we divide by 9 we have to flip the less than sign because we have to flip it if we multiply or divide.
This gives us the answer, x>=-46/9 which does not simplify any further
