Alana incorrectly simplified the expression (-14a + 12) - (-10a + 13) as -24a + 25 describe her error

The answer should be -4a-1. This is because you have to open the box.

-(-10a+13)

Two negatives become positive so she should have had -14+10 to make -4 and 12-13 to make -1. A negative and positive together, the negative always wins so that why you subtract.

Step-by-step explanation:

Coordinates of points A and C are (-8, 6) and (2, 5).

If a point B intersects the segment AB in the ratio of 2 : 5

Then coordinates of the point B will be,

x =

and y =

where and are the coordinates of the extreme end of the segment and a point divides the segment in the ratio of m : n.

For the coordinates of point B,

x =

  =

y =

  =

Therefore, coordinates of pint B will be,
