Question

Which values are solutions to the inequality below? Check all that
Sqrt x>=9

Answer 1

Answer: it’s 81 & 100.

Explanation:

a p e x

Answer 2

Given:

The given inequality is
`√(x) \geq 9`

We need to determine the solution to the inequality.

Solution of the inequality:

The solution of the inequality can be determined by solving the inequality.

Let's equate the inequality.

Thus, we have;

`√(x) =9`

Squaring on both sides, we get;

`x=9^2`

Simplifying, we get;

`x=81`

Let us check the solution in the original expression.

Substituting
`x=81` in
`√(x) \geq 9`, we get;

`√(81)\geq 9`

`9\geq 9`

Thus, the solution satisfies the inequality.

Thus, the solution to the inequality is 81.

Hence, Option E is the correct answer.
