Question

Twenty times y is at most 100 in interval notation

Answer 1

Answer:

$y\in (-\infty ,5]$

Step-by-step explanation:

In this problem, we need to write "Twenty times y is at most 100 in interval notation ".

20 times y means, 20y

Atmost means an inequality which is $\le$

ATQ,

$20\times y\le 100$

i.e.

$20y\le 100\\\\y\le 5$

We can also write it as :

$y\in (-\infty ,5]$

Hence, the required interval notation is $y\in (-\infty ,5]$.

Answer 2

The interval notation is $\rm y \epsilon (\infty,6]$.

What is interval notation?

The Interval notation is a method to define a set of numbers between a lower limit and an upper limit by using end-point values.

"Twenty times y is at most 100 in interval notation ".

Here, 20 times y means, 20y at most means an inequality.

Therefore,

The inequality is;

$\rm 20 \times y\leq 100\\\\20y\leq 100\\\\y \leq \dfrac{100}{20}\\\\y\leq 5$

Hence, the required interval notation is $\rm y \epsilon (\infty,6]$.
