The intersection of 2 lines is a point so A. Because that’s where the lines meet then if they keep going they shouldn’t touch again.
Answer:
12!
Step-by-step explanation:
The height of a tree is 10
10
meters long and it grows 1
1
cm in a year.
Then its height after one year = 10
10
meters 1
1
cm
Its height after 3
3
years = 10
10
meters 3
3
cm
Its height after 6
6
years = 10
10
meters 6
6
cm
Its height after x
x
years = 10
10
meters x
x
cm
Where x
x
represents an unknown number. From the last line, we can find height of the tree after a certain number of years by taking x
x
equal to that number. For example, we simply let x=15
x
=
15
, 25
25
and 55
55
. Thus, the value of x
x
depends on our choice. We can give x
x
any value or number we want. In other words, the value of x
x
is not fixed, it varies from one situation to the other. Therefore, we call x
x
a variable whereas 10
10
is a fixed number whole value does not change. So 10
10
therefore is called a constant.

Good question.
Basically, your money.
Algebra is pretty useful for a number of problems in your job and managing your money.
Your teacher probably gives you "real world problems" that apply principles in algebra to the real world.
That being said, if you are pursuing a career in STEM fields, then you definitely need to learn algebra and a few other higher level math courses.
If you're not pursuing a career in STEM, then you learn algebra for your money, which is pretty important to everyone.
