What is the number of distinguishable letters in the word alphabet

1 answer:

4 0

First, we have to find how many different letters does the world alphabet have, we are not going to count the letters that repeat.
It has 7 different letters (not 8, because the letter "A" appears two times.
The formula would be:
$P=7!$
$P=7*6*5*4*3*2*1$
$P=5,040$
That's your answer!

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15? Drag and drop each choice in

nexus9112 [7]

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.

<h3>How can the slope of the line be calculate?</h3>

The slope of the line is been given as −3x+5y=−15

Then $y= \frac{3}{5x} -3$ , hence the slope is $\frac{3}{5}$
