A man ordered 4 times as many boxes of ballpoint pens as boxes of felt-tip pens. Ballpoint pens cost $4.41 per box, and felt-tip
natka813 [3]

Answer:

3

Step-by-step explanation:

Let x = # of boxes of felt-tip pens.

(x)(3.44)+(4x)(4.41) = 63.24

21.08x = 63.24

x = 3

Because x = 3, the man bought 3 boxes of felt-tip pens and 12 boxes of ballpoint pens.

If x =&gt; y and y =&gt; z, which statement must be true?
Kruka [31]

The operator \geq is transitive, which means exactly that

x \geq y,\quad y\geq z \implies x \geq z

That's the only thing you can deduce from your statement.

What is the inverse of the equation y=x²-4, x≤ 0​
Lina20 [59]

The inverse of the equation y = x² - 4, x≤ 0​ is y = \sqrt{x + 4

<h3>How to determine the inverse of the equation?</h3>

The equation is given as:

y = x² - 4, x≤ 0​

Swap the x and y values

x = y² - 4

Add 4 to both sides

y² = x + 4

Take the square root of both sides

y = \sqrt{x + 4

Hence, the inverse of the equation y = x² - 4, x≤ 0​ is y = \sqrt{x + 4
