How would I Find AE-DC
If A is -3
If E is 2
If D is 0
If C is 1
What would be my answer would i minus them and then divide over 2 or what thanks for your time!1
Plese Reply ASAP
 
I do not see anything that involves a midpoint. Perhaps, you did not type the entire exercise.

To find the value of the expression AE - DC, simply substitute the given values for each of these four symbols and then do the arithmetic.

(-3)(2) - (0)(1)

There is no division here, either, so I'm thinking that you have not typed the actual question with which you would like help.

What are you trying to do?

 
Re: Geomtery Help on Midpoint Help ASAP!

It's just a number line and says Find AE -DC
so would it be right if I got 2 as my final answer
I took -3 - 2 and got -2
and for the bottom i took 0-1 and got -1
So I divided -2
-1 and got 2
Is this right?

From where are you getting the symbols A, E, D, and C?



... so would it be right if I got 2 as my final answer ...Not from the information that you've stated.


... I took -3 - 2 and got -2 ... Subtracting 2 from -3 results in -5, not -2.

... for the bottom i took 0-1 and got -1<<<< The "bottom" of what? A Real number line has no "bottom".

... So I divided ...<<<< I previously told you that there are no divisions in the expression AE - DC.

I still have no idea what you're trying to accomplish.

You wrote that you're trying to find the value of the expression AE - DC.

You gave values for each of these four symbols.

If A is -3 and E is 2, then the product AE is -6.

If D is 0 and C is 1, then the product DC is 0.

If you subtract zero from -6, the result is -6.

Therefore, based on what you've stated, so far, the value of AE minus DC is -6.

If you would like more help with this exercise, then please provide ALL of the given information, including a detailed description of the given diagram.
 
The diagram is a number line with letter on top of some numbers, and they have number below them indicating what numbers they are
I did the equation again and got -6, is this correct?

Also if I was to find BF on this number line and
B is -2
F is 3.5

So I solved and got -2-3.5= -5.5
So BF is -5.5
Is this correct?

Thanks

Is this correct? <<<< Almost! Distances (lengths) cannot be negative.

So, on the Real number line, the distance from the number -2 to the number 3.5 is 5.5 units.
