What two numbers add to equal ten and multiplies to equal negative seven?
lawyer [7]
Okay ShallBeTheLast, what we will do will involve a lot of simple plug and play kind of actions.
To start we must notice one number must be negative and the other should be positive, because the multiplied number is a negative.

Next, lets multiply number that have a sum of 10 (keep in mind one has to be negative and the other has to be positive).

-1 * 10 = -10 false
-2 * 12 = -24 false
-3 * 13 = -39 false
notice that no number working and it's only getting farther away.
There is no solution for this that involves to integers.

I think you might of wrote the question backwards.
If that is the case we would run numbers like.....
-1 * (-6) = 7 false
-2 * (-5) = 10 true!!!!

-2 and -5 would work

Given Trinagle ABC with A(-4, -2), B(4,4), and C(18,-8), answer the following questions.
True [87]
For the answer to the question above, the slope of segment AC is  (-6/22) = -3/11.

The slopes of perpendicular lines are negative reciprocals, so 
you know that the slope of the perpendicular bisector will be 11/3.

The midpoint of segment AC is  (7, -5).

Now you have the slope of the perpendicular bisector, and a
point on it.  You should be able to complete the equation now.

Notice how sneaky this question is.  You don't need to know
point-B at all, and you don't even need to know that there's
any triangle.  All you need to know is points  A  and  C.
