Question

64 less than y is no less than −128 Written in interval notation

Answer 1

Answer:

$y\in [-64,\infty)$ .

Step-by-step explanation:

The given statement is "64 less than y is no less than −128". It means 64 less than y is greater than or equal to −128.

$y-64\geq -128$

Add 64 both sides.

$y-64+64\geq -128+64$

$y\geq -64$

It means possible value of y is greater than or equal to -64.

$y\in [-64,\infty)$

Therefore, the required interval is $[-64,\infty)$.
