Point O is the center of dilation. Triangle D E F is dilated to create smaller triangle D' E' F'. The length of O F' is 3. The length of F' F is 7. What is the scale factor of the dilation of triangle DEF? Three-tenths (3/10)

Three-sevenths (3/7)

Seven-thirds (7/3)

Seven (7)

d is correct

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

0.02
