Answer:

3 positive integers

Step-by-step explanation:

-2x + 1 ≥ -6

-2x≥-6-1

-2x≥-7

2x≥7

Divide both sides by 2

2x/2≥7/2

x≥7/2

x≥3.5

By interpretation, it reads x greater than or equal to 3.5

That's 1, 2, 3 and even 3.5

That's 3 positive integers

Which choice is equivalent to the expression below? -25 <br>

Pavel [41]

Answer:

Option A.

Step-by-step explanation:

The given expression is

$-25$

According to the reflexive property of equality, all values are equal to itself.

a = a

where, a be any real number.

Using the reflexive property we can say that

$-25=-25$

It means -25 is equal or equivalent to -25.

Therefore, the correct option is A.

Note: If the given expression is $\sqrt{-25}$ , then

$\sqrt{-25}=\sqrt{25}\sqrt{-1}$ $[\because \sqrt{ab}=\sqrt{a}\sqrt {b}]$

$\sqrt{-25}=5i$ $[\because \sqrt{-1}=i]$

Then the correct option is B.
