Ali says if two lines share a point they cannot be parallel do you agree explain

Answers

Yes, parallel lines do not touch each other ever.

How are parallel straight lines related?

Parallellines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

We are given that Ali says if two lines share a point they cannot be parallel .

Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.

When you slice an object horizontally, you cut it parallel to ground.

We know that parallel linesdo not touch each other ever.

so that's make ali statement correct.

What is 345 written as a percent

Answers

Answer: 34500%.

Step-by-step explanation:

When we convert a number into percent , we multiply it by 100.

For example: To convert 0.56 into percent, we have

$0.56*100=56\%$

Let's take one more example , to convert 12 into percent , we have

$12*100=1200\%$

The given number : 345

So to convert 345 into percent , we just multiply it by 100 , we get

$345*100=34500\%$

Hence, 345 is 34500%.

Thus , the correct answer is 34500%.

I think this is correct 345 = 34500%

It'a an arithmetic sequence:

$\boxed{a_n=(5)/(3)n-(8)/(3)}$
