no, you want a counter example, so you want something that adds two primes together, but ends with a COMPOSITE solution.

so c ? cuz its 2 prime

C doesnt have a 2 in it, but it is the correct answer because 3 is prime, and a 11 is prime, but 14 is composite.

Think about these three cases:

Lines intersect at one point - YES

Lines are parallel - NO

Lines are the same line - NO

So, it's not always, but it's not never either...so it's ______

You are correct, two lines can be parallel. So they will intersect only some of the time.

yep, you got it! :)

Answer 8

Sometimes. But let's break this down a bit.

1. y=x+1, y=x-1
How many solutions are there for x?

2. y=x, y=-x
How many solutions are there for x?

3. y=x, 2y=2x
How many solutions are there for x?
