An equal lateral triangle with a perimeter of 15 units is graft on according to grade the triangle is dilated by scale factor of .25 with the gorging as centerpoint dilation if XY represents location of any point original version which order a pair the corner of corresponding point on this shape

(0.25x, 0.25y)

Step-by-step explanation:

Since the origin is the center of the scale factor of dilation, we don't need to add or subtract anything

Multiplying the x and y values of the ordered pair by 0.25 represents what the value would be with the scale factor, meaning multiplication.

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
