the coordinates of the vertices of triangle abc are a(9, –10), b(–15, 0), and c(15, 10). a dilation centered at (0, 0) is perfomed on triangle abc to produce triangle a'b'c'. the coordinates of the vertices of triangle a'b'c' are a'(13.5, –15), b'(–22.5, 0), and c'(22.5, 15). find the scale factor.

The answer is D. 1.5

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.
