A number r is more than 0 or less than or equal to ‐8

Butoxors [25]

Answer

-8 $\geq$ r > 0

Step-by-step explanation:

you know that r is less than or equal to -8, so you write that, and then you know that r is also greater than 0, so then you add that to it, and then you have the answer. r will be in the middle because it is the range of what are can be.

When you are trying to find the endpoint when given the midpoint and one point, what would the new formula be? Manipulate the fo

MariettaO [177]

Answer:

$(x_2,y_2) = (2x_m - x_1 ,2y_m - y_1 )$

Step-by-step explanation:

Given

$\left(\frac{x_1+\:x_2}{2},\:\:\frac{y_{1\:}+y_2}{2}\right)\:=\:\left(x_m,\:y_m\right)$

Required

Determine x2, y2

Start by splitting the expression

$x_m = \left(\frac{x_1+\:x_2}{2})$ and $y_m = (\frac{y_{1\:}+y_2}{2})$

Solving for x2 in $x_m = \left(\frac{x_1+\:x_2}{2})$

Multiply through by 2

$2 * x_m = \frac{x_1 + x_2}{2} * 2$

$2x_m = x_1 + x_2$

Make x2 the subject;

$x_2 = 2x_m - x_1$

Similarly:

$y_m = (\frac{y_{1\:}+y_2}{2})$

Multiply through by 2

$2 * y_m = \frac{y_1 + y_2}{2} * 2$

$2y_m = y_1 + y_2$

Make y2 the subject;

$y_2 = 2y_m - y_1$

Hence:

$(x_2,y_2) = (2x_m - x_1 ,2y_m - y_1 )$
