The coordinates for point a are. explain how these numbers tell you the position of point a using the graph?

You can see that the distance of Point A above the horiz. axis is 5 units.  The same point is 3 units to the left of the y-axis.  Thus, the coordinates of Point A are (-3,5).

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
