Can you pls help me with this question thank youu

Answer 1

Remember that

The word " at most" means ----> less than or equal to

so

the inequality is

`t\leq8`

The solution of the inequality is the interval (-infinite,8]

but remember that the variable t cannot be a negative number

so

the solution is the interval [0,8]

In a number line, the solution is the shaded area at the right of t=0 (closed circle) and at the left of t=8 (closed circle)
