Question

HELP ASAP PLEASE

Answer 1

Because then you'd be dividing by zero. Dividing by zero is bad.

Answer 2

huh

Answer 3

When you plug in -1/2 into the denominator for x, you get -1 + 1
This becomes zero.
Anything divided by zero is zero.

Answer 4

Can you show step by step and help me solve it

Answer 5

When you graph f(x)=0 ,this can be any term. It covers the whole axis.

/K I'll show it step by step, 1 sec.

Answer 6

thank you

Answer 7

for part 1 and 2 please

Answer 8

2x+3x+1 / 2x + 1

Part 2
f(x)= -1/2
Meaning, replace x with -1/2 in the equation.
You get -1-1.5+1 / -1 + 1
Simplify (one minus one is zero on bottom, -1.5 is what is left on top)
-1.5/0
Anything -ever- divided by zero is zero. 1,000,000/0 is zero.
/
Part 1

Simplify 2x+3x+1 for the top, Which is 5x +1
Bottom is still 2x+1, nothing left to simplify.

So now you have 5x+1/2x+1
1's cancel out. So your answer for part 1 is 5/2x

I believe this is all correct.

Answer 9

thank you so much!

Answer 10

i have a few more want to help?

Answer 11

"Anything -ever- divided by zero is zero. 1,000,000/0 is zero. "

WRONG.
Anything divided by zero is undefined. You can't do it. The world implodes.

Answer 12

Undefined, yes yes. Like I said, because it covers the whole axis. We don't want the world imploding or anything of that matter.
