Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

-11 > 1 + a

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Subtract 1 on both sides:                    -12 > a
  2. Rewrite:                                               a < -12

Here we see that any value <em>a</em> smaller than -12 would work as a solution to the inequality.

What are the coordinates of the point on the directed line segment from (-9, -1)(−9,−1) to (-9, -10)(−9,−10) that partitions the
mihalych1998 [28]

Answer:

Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-7).

Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-19).

Step-by-step explanation:

Given points are (-9,-1) and (-9,-10)

If a point divides the line segment by joining two points (x₁,y₁) and (x₂,y₂)  into a ratio m:n internally.

Then the point of the coordinate is (\frac{m.x_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}).

If a line segment is externally divided into a point by joining two points (x₁,y₁) and (x₂,y₂) with m: n ratio.

Then the point of the coordinate is (\frac{m.x_2-nx_1}{m-n},\frac{my_2-ny_1}{m-n}).

Internally

The co-ordinate of the point is (\frac{(-9)\times2+(-9)\times 1}{2+1},\frac{(-10)\times 2+(-1)\times 1}{2+1})

                                                 =(-9,-7)

Externally

The co-ordinate of the point is (\frac{(-9)\times2-(-9)\times 1}{2-1},\frac{(-10)\times 2-(-1)\times 1}{2-1})

                                                   =  (-9,-19)
