PLEASE HELP QUICK Absolute Value Equations and Inequalities
The V-shaped bottom of a river can be modeled with this absolute value equation, where d represents the depth of the river
bottom and s represents the horizontal distance from the left shore, in feet.
D = 1/5 |s - 250| - 50. The harbor master wants to place buoys where the river bottom is 20 feet below surface of the water. Complete the absolute value of the equation to find the horizontal distance from the left shore which they buoys should be placed

The bottom of a river makes a V-shape that can be modeled with the absolute value function, d(h) = 1/5|h - 240| - 48, where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet).

Step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
