How do you solve and write the following in interval notation: t is at least 10 and at most 22?

Use the inequality symbols.

Explanation:

Basically, since t is at least 10,

t >= 10.

And since it is at most 22,

t <= 22.

So the final answer is: 10 <= t <= 22

Hope this helps you.

10 <= t <=2210t22

Explanation:

'At least 1010', means that tt can be equal to 1010 or is more than 1010.

'At most 2222' means that tt can be equal to 2222, but can also be less than 2222.

This gives the lower limit and the upper limit to the interval.

10 <= t <=2210t22

t =[10,22]t=[10,22]

Explanation:

We are told that tt is at least 10 and at most 22.

Hence, t>=10 and t<=22 -> 10<= t <=22t10andt2210t22

This can be written in interval notation as:

t =[10,22]t=[10,22]
