One of two things:
-There is no solution because they are parallel lines
- OR There is infinite solutions because they are the same line.
20% x 50 =(20 / 100) x 50 = (20 x 50) / 100 = 1000 / 100 = 10
answer is 10
It can have however many x intercepts it wants,
<span>BUT, to be a function it must pass the vertical line test. </span>
<span>this means you have to look at the graph and see if a vertical line drawn anywhere hits the graph more than once. </span>
<span>if it hits it more than once, it is NOT a function.
</span>
An example is a polynomial function to the infinite degree. That is
f(x) = lim (n --> infinity) [ x^n]
but only 1 y intercept (vertical line test remember)
You combine like terms.
-2x+9x
whatever answer that is you then combine the like terms -9+-1 the you just make an expression out of them.
